Here is, I. The fatigue of Israel by a long march round the land of Edom, because they could not obtain passage through it the nearest way: The soul of the people was much discouraged because of the way, Num. 21:4. Perhaps the way was rough and uneven, or foul and dirty; or it fretted them to go far about, and that they were not permitted to force their passage through the Edomites’ country. Those that are of a fretful discontented spirit will always find something or other to make them uneasy.

II. Their unbelief and murmuring upon this occasion, Num. 21:5. Though they had just now obtained a glorious victory over the Canaanites, and were going on conquering and to conquer, yet they speak very discontentedly of what God had done for them and distrustfully of what he would do, vexed that they were brought out of Egypt, that they had not bread and water as other people had by their own care and industry, but by miracle, they knew not how. They have bread enough and to spare; and yet they complain there is no bread, because, though they eat angels’ food, yet they are weary of it; manna itself is loathed, and called light bread, fit for children, not for men and soldiers. What will those be pleased with whom manna will not please? Those that are disposed to quarrel will find fault where there is no fault to be found. Thus those who have long enjoyed the means of grace are apt to surfeit even on the heavenly manna, and to call it light bread. But let not the contempt which some cast upon the word of God cause us to value it the less: it is the bread of life, substantial bread, and will nourish those who by faith feed upon it to eternal life, whoever calls it light bread.

III. The righteous judgment which God brought upon them for their murmuring, Num. 21:6. He sent fiery serpents among them, which bit or stung many of them to death. The wilderness through which they had passed was all along infested with those fiery serpents, as appears, Deut. 8:15. But hitherto God had wonderfully preserved his people from receiving hurt by them, till now that they murmured, to chastise them for which these animals, which hitherto had shunned their camp, now invade it. Justly are those made to feel God’s judgments that are not thankful for his mercies. These serpents are called fiery, from their colour, or from their rage, or from the effects of their bitings, inflaming the body, putting it immediately into a high fever, scorching it with an insatiable thirst. They had unjustly complained for want of water (Num. 21:5), to chastise them for which God sends upon them this thirst, which no water would quench. Those that cry without cause have justly cause given them to cry out. They distrustfully concluded that they must die in the wilderness, and God took them at their word, chose their delusions, and brought their unbelieving fears upon them; many of them did die. They had impudently flown in the face of God himself, and the poison of asps was under their lips, and now these fiery serpents (which, it should seem, were flying serpents, Isa. 14:29) flew in their faces and poisoned them. They in their pride had lifted themselves up against God and Moses, and now God humbled and mortified them, by making these despicable animals a plague to them. That artillery is now turned against them which had formerly been made use of in their defence against the Egyptians. He that brought quails to feast them let them know that he could bring serpents to bite them; the whole creation is at war with those that are in arms against God.

IV. Their repentance and supplication to God under this judgment, Num. 21:7. They confess their fault: We have sinned. They are particular in their confession: We have spoken against the Lord, and against thee. It is to be feared that they would not have owned the sin if they had not felt the smart; but they relent under the rod; when he slew them, then they sought him. They beg the prayers of Moses for them, as conscious to themselves of their own unworthiness to be heard, and convinced of the great interest which Moses had in heaven. How soon is their tone altered! Those who had just before quarrelled with him as their worst enemy now make their court to him as their best friend, and choose him for their advocate with God. Afflictions often change men’s sentiments concerning God’s people, and teach them to value those prayers which, at a former period, they had scorned. Moses, to show that he had heartily forgiven them, blesses those who had cursed him, and prays for those who had despitefully used him Herein he was a type of Christ, who interceded for his persecutors, and a pattern to us to go and do likewise, and thus to show that we love our enemies.

V. The wonderful provision which God made for their relief. He did not employ Moses in summoning the judgment, but, that he might recommend him to the good affection of the people, he made him instrumental in their relief, Num. 21:8; 9. God ordered Moses to make the representation of a fiery serpent, which he did, in brass, and set it up on a very long pole, so that it might be seen from all parts of the camp, and every one that was stung with a fiery serpent was healed by looking up to this serpent of brass. The people prayed that God would take away the serpents from them (Num. 21:7), but God saw fit not to do this: for he gives effectual relief in the best way, though not in our way. Thus those who did not die for their murmuring were yet made to smart for it, that they might the more feelingly repent and humble themselves for it; they were likewise made to receive their cure from God, by the hand of Moses, that they might be taught, if possible, never again to speak against God and Moses. This method of cure was altogether miraculous, and the more wonderful if what some naturalists say be true, that looking upon bright and burnished brass is hurtful to those that are stung with fiery serpents. God can bring about his purposes by contrary means. The Jews themselves say that it was not the sight of the brazen serpent that cured them, but, in looking up to it, they looked up to God as the Lord that healed them. But there was much of gospel in this appointment. Our Saviour has told us so (John 3:14; 15), that as Moses lifted up the serpent in the wilderness so the Son of man must be lifted up, that whosoever believeth in him should not perish. Observe then a resemblance,

1. Between their disease and ours. The devil is the old serpent, a fiery serpent, hence he appears (Rev. 12:3) as a great red dragon. Sin is the biting of this fiery serpent; it is painful to the startled conscience, and poisonous to the seared conscience. Satan’s temptations are called his fiery darts, Eph. 6:16. Lust and passion inflame the soul, so do the terrors of the Almighty, when they set themselves in array. At the last, sin bites like a serpent and stings like an adder; and even its sweets are turned into the gall of asps.

2. Between their remedy and ours. (1.) It was God himself that devised and prescribed this antidote against the fiery serpents; so our salvation by Christ was the contrivance of Infinite Wisdom; God himself has found the ransom. (2.) It was a very unlikely method of cure; so our salvation by the death of Christ is to the Jews a stumbling-block and to the Greeks foolishness. It was Moses that lifted up the serpent in the wilderness, so the law is a schoolmaster to bring us to Christ, and Moses wrote of him, John 5:4-6. Christ was lifted up by the rulers of the Jews, who were the successors of Moses. (3.) That which cured was shaped in the likeness of that which wounded. So Christ, though perfectly free from sin himself, yet was made in the likeness of sinful flesh (Rom. 8:3), so like that it was taken for granted that this man was a sinner, John 9:24. (4.) The brazen serpent was lifted up; so was Christ. He was lifted up upon the cross (John 12:33, 34), for his was made a spectacle to the world. He was lifted up by the preaching of the gospel. The word here used for a pole signifies a banner, or ensign, for Christ crucified stands for an ensign of the people, Isa. 11:10. Some make the lifting up of the serpent to be a figure of Christ’s triumphing over Satan, the old serpent, whose head he bruised, when in his cross he made an open show of the principalities and powers which he had spoiled and destroyed, Col. 2:15.

3. Between the application of their remedy and ours. They looked and lived, and we, if we believe, shall not perish; it is by faith that we look unto Jesus, Heb. 12:2. Look unto me, and be you saved, Isa. 45:22. We must be sensible of our wound and of our danger by it, receive the record which God has given concerning his Son, and rely upon the assurance he has given us that we shall be healed and saved by him if we resign ourselves to his direction. The brazen serpent’s being lifted up would not cure if it was not looked upon. If any pored on their wound, and would not look up to the brazen serpent, they inevitably died. If they slighted this method of cure, and had recourse to natural medicines, and trusted to them, they justly perished; so if sinners either despise Christ’s righteousness or despair of benefit by it their wound will, without doubt, be fatal. But whoever looked up to this healing sign, though from the outmost part of the camp, though with a weak and weeping eye, was certainly healed; so whosoever believes in Christ, though as yet but weak in faith, shall not perish. There are weak brethren for whom Christ died. Perhaps for some time after the serpent was set up the camp of Israel was molested by the fiery serpents; and it is the probable conjecture of some that they carried this brazen serpent along with them through the rest of their journey, and set it up wherever they encamped, and, when they settled in Canaan, fixed it somewhere within the borders of the land; for it is not likely that the children of Israel went so far off as this was into the wilderness to burn incense to it, as we find they did, 2 Kgs. 18:4. Even those that are delivered from the eternal death which is the wages of sin must expect to feel the pain and smart of it as long as they are here in this world; but, if it be not our own fault, we may have the brazen serpent to accompany us, to be still looked up to upon all occasions, by bearing about with us continually the dying of the Lord Jesus.
