David was certainly the penman of this psalm, and
it has in it the genuine spirit of the man after God's own heart;
it is a solemn vow which he made to God when he took upon him the
charge of a family and of the kingdom. Whether it was penned when
he entered upon the government, immediately after the death of Saul
(as some think), or when he began to reign over all Israel, and
brought up the ark to the city of David (as others think), is not
material; it is an excellent plan or model for the good government
of a court, or the keeping up of virtue and piety, and, by that
means, good order, in it: but it is applicable to private families;
it is the householder's psalm. It instructs all that are in any
sphere of power, whether larger or narrower, to use their power so
as to make it a terror to evil-doers, but a praise to those that do
well. Here is, I. The general scope of David's vow,
A psalm of David.
1 I will sing of mercy and judgment: unto thee, O Lord, will I sing. 2 I will behave myself wisely in a perfect way. O when wilt thou come unto me? I will walk within my house with a perfect heart. 3 I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me. 4 A froward heart shall depart from me: I will not know a wicked person. 5 Whoso privily slandereth his neighbour, him will I cut off: him that hath a high look and a proud heart will not I suffer. 6 Mine eyes shall be upon the faithful of the land, that they may dwell with me: he that walketh in a perfect way, he shall serve me. 7 He that worketh deceit shall not dwell within my house: he that telleth lies shall not tarry in my sight. 8 I will early destroy all the wicked of the land; that I may cut off all wicked doers from the city of the Lord.
David here cuts out to himself and others a pattern both of a good magistrate and a good master of a family; and, if these were careful to discharge the duty of their place, it would contribute very much to a universal reformation. Observe,
I. The chosen subject of the psalm
(
1. Of God's mercy and judgment, and then it looks back upon the dispensations of Providence concerning David since he was first anointed to be king, during which time he had met with many a rebuke and much hardship on the one hand, and yet, on the other hand, had had many wonderful deliverances wrought for him and favours bestowed upon him; of these he will sing unto God. Note, (1.) God's providences concerning his people are commonly mixed—mercy and judgment; God has set the one over-against the other, and appointed them April-days, showers and sunshine. It was so with David and his family; when there was mercy in the return of the ark there was judgment in the death of Uzza. (2.) When God in his providence exercises us with a mixture of mercy and judgment it is our duty to sing, and sing unto him, both of the one and of the other; we must be suitably affected with both, and make suitable acknowledgments to God for both. The Chaldee-paraphrase of this is observable: If thou bestowest mercy upon me, or If thou bring any judgment upon me, before thee, O Lord! will I sing my hymns for all. Whatever our outward condition is, whether joyful or sorrowful, still we must give glory to God, and sing praises to him; neither the laughter of a prosperous condition nor the tears of an afflicted condition must put us out of tune for sacred songs. Or,
2. It may be understood of David's mercy and judgment; he would, in this psalm, promise to be merciful, and just, or wise, for judgment is often put for discretion. To do justly and love mercy is the sum of our duty; these he would covenant to make conscience of in that place and relation to which God had called him and this in consideration of the various providences of God that had occurred to him. Family-mercies and family-afflictions are both of them calls to family-religion. David put his vow into a song or psalm, that he might the better keep it in his own mind and frequently repeat it, and that it might the better be communicated to others and preserved in his family, for a pattern to his sons and successors.
II. The general resolution David took up to
conduct himself carefully and conscientiously in his court,
1. A good purpose concerning his
conversation—concerning his conversation in general (how he would
behave himself in every thing; he would live by rule, and not at
large, not walk at all adventures; he would, though a king, by a
solemn covenant bind himself to his good behaviour), and concerning
his conversation in his family particularly, not only how he would
walk when he appeared in public, when he sat in the throne, but how
he would walk within his house, where he was more out of the
eye of the world, but where he still saw himself under the eye of
God. It is not enough to put on our religion when we go abroad and
appear before men; but we must govern ourselves by it in our
families. Those that are in public stations are not thereby excused
from care in governing their families; nay, rather, they are more
concerned to set a good example of ruling their own houses
well,
2. A good prayer: O when wilt thou come
unto me? Note, It is a desirable thing, when a man has a house
of his own, to have God come to him and dwell with him in it; and
those may expect God's presence that walk with a perfect
heart in a perfect way. If we compare the account which
the historian gives of David (
III. His particular resolution to practise
no evil himself (
IV. His further resolution not to keep bad
servants, nor to employ those about him that were vicious. He will
not countenance them, nor show them any favour, lest thereby he
should harden them in their wickedness, and encourage others to do
like them. He will not converse with them himself, nor admit them
into the company of his other servants, lest they should spread the
infection of sin in his family. He will not confide in them, nor
put them in power under him; for those who hated to be reformed
would certainly hinder every thing that is good. When he comes to
mention particulars he does not mention drunkards, adulterers,
murderers or blasphemers; such gross sinners as these he was in no
danger of admitting into his house, nor did he need to covenant
particularly against having fellowship with them; but he mentions
those whose sins were less scandalous, but no less dangerous, and
in reference to whom he needed to stand upon his guard with caution
and to behave himself wisely. He will have nothing to do, 1. With
spiteful malicious people, who are ill-natured, and will bear a
grudge a great while, and care not what mischief they do to those
they have a pique against (
V. His resolution to put those in trust
under him that were honest and good (
VI. His resolution to extend his zeal to
the reformation of the city and country, as well as of the court
