I will not set a wicked thing before my eyes After having protested, that in leading a private life, he would practice virtue and righteousness, even as it becomes good princes to begin with this, he now adds, that in executing the office of prince, he will be the enemy of all injustice and wickedness. To set a wicked thing before one's eyes, is equivalent to purposing to do something that is wicked. He therefore declares, that he will turn away from all wickedness; and it is certain, that no man can be a just and an impartial punisher of wrongdoing, but he who abhors it with all his heart. Whence it follows that kings, in order to the performance of their duty, must keep themselves entirely free from all consent to wickedness. Some join to the first sentence the word svh, asoh, which we translate work, and supply the letter l, lamed; as if it had been said, I will not set before my eyes any wickedness to do it, or, nothing wicked will be acceptable to me to execute it. But the other sense is more probable, which is, that David, after having declared that he will not suffer any iniquity before his eyes, immediately adds for the sake of confirmation, that he will be an enemy to all injustice. If the last clause is referred to the persons who turn aside, there is a change of the number. It may, however, be explained of the work itself, implying that he would never have any share in wicked defections from the path of rectitude.

I will set no wicked thing before mine eyes - That is, I will propose no wicked thing to be done; I will have no such object in view; I will employ no one to do that which is wrong. The margin, as the Hebrew, is, "thing of Belial." See the notes at Psalm 41:8. It here means that which is worthless, bad, wicked. He would have no wicked aim; he would not look upon a wicked thing for a moment, or with the least favor.
I hate the work of them that turn aside - All their doings, motives, plans. The word rendered "turn aside" means to turn out of the way; out of the right path: Wanderers - transgressors - those who leave the path of truth and honesty.
It shall not cleave to me - I will have nothing to do with it. It shall not he allowed to attach itself to me. A wicked plan or purpose is thus represented as having a tendency to fasten itself on a man, or to "stick to him" - as pitch, or wax, as a "burn" does.

I will set no wicked thing before mine eyes - I will undertake no unjust wars; will enter into no sinful alliances; will not oppress my subjects by excessive taxation, to support extravagance in my court. I will not look favourably on things or words of Belial. What is good for nothing or evil in its operation, what is wicked in its principle, and what would lead me away from righteousness and truth, I will never set before my eyes.
Them that turn aside - I shall particularly abominate the conduct of those who apostatize from the true religion, and those who deny its Divine authority, and who live without having their conduct governed by its influence, such shall never he put in a place of political trust or confidence by me.

I will set no wicked thing before mine eyes: I hate (c) the work of them that turn aside; [it] shall not cleave to me.
(c) He shows that magistrates do not do their duties, unless they are enemies to all vice.

I will set no wicked thing before mine eyes, Either the eyes of the body, which are the inlets of lust and are easily caught with objects that inflame the heart, and should be turned aside from beholding vanity; or the eyes of the mind; so the Targum,
"I will not propose to my heart;''
or, as Kimchi,
"in my thought'',
that is, I will not set up an evil thing in my imagination, to dwell upon in my thoughts, and take delight and pleasure in meditating upon it; or set it before me, to imitate as a pattern, to work by, and copy after: Christ did not so; he set the Lord always before him, Psalm 16:8, not anything of Belial (k) or Satan, as the phrase here may be rendered; no, he always bid Satan, or anything of his, be gone, and get behind him, Matthew 4:10.
I hate the work of them that turn aside; from God, and from his law; from the paths of religion, truth, and virtue; and from the Gospel, and a profession of it; such are not fit for the kingdom of God, and in these God and Christ have no pleasure, Hebrews 10:38,
it shall not cleave to me; neither the wicked thing, or thing of Belial, nor the work of apostasy; that is, he would have no familiarity nor fellowship with it; not come near it, nor connive at it, but hate and abhor it: the Jews said, an evil disease, or a thing of Belial, "cleaveth fast unto him", Psalm 41:8, but they were mistaken.
