(28) Thou shalt also decree a thing.--As, for instance, in the memorable case of Abraham's intercession for Sodom, to which there is not improbably an allusion here.

Verse 28. - Thou shalt also decree a thing, and it shall be established unto thee. Whatever thou resolvest on, i.e., God shall ratify with his authority, and bring to pass in due time for thy benefit - a promise which has certainly "a touch of audacity" about it (Cook). David is less bold, but intends to give the same sort of encouragement when he says, "Delight thyself in the Lord, and he shall give thee the desires of thine heart; commit thy way unto the Lord; trust also in him; and he shall bring it to pass (Psalm 37:4, 5). And the light shall shine upon thy ways. Job had complained of the "darkness" by which his path was shadowed (Job 19:8). Eliphaz promises that this cause of complaint shall be removed. Job's way shall be "made plain before his face." A bright light shall illumine it - a light that shall ever "shine more and more unto the perfect day" (Proverbs 4:18).

22:21-30 The answer of Eliphaz wrongly implied that Job had hitherto not known God, and that prosperity in this life would follow his sincere conversion. The counsel Eliphaz here gives is good, though, as to Job, it was built upon a false supposition that he was a stranger and enemy to God. Let us beware of slandering our brethren; and if it be our lot to suffer in this manner, let us remember how Job was treated; yea, how Jesus was reviled, that we may be patient. Let us examine whether there may not be some colour for the slander, and walk watchfully, so as to be clear of all appearances of evil.Thou shalt also decree a thing, and it shall be established unto thee,.... Strictly speaking, this is only true of God, whose decrees are unfrustrable, whose counsel shall stand, and the thoughts of his heart be established to all generations; and frequently so it is, according to an usual saying, man appoints, but God disappoints; this may be understood of Job, either as a civil magistrate, that he should decree a thing in a court of judicature with so much wisdom and equity, that it should stand firm and sure, and, though made on earth, should be ratified in heaven, as the decrees and doctrines of the apostles of Christ are said to be, Matthew 16:19; see Proverbs 8:15; or, as a private man in civil affairs, signifying that he should be so guided by the Lord, and prospered and succeeded in all his ways and works, that what he determined to do, and formed a scheme for the execution of, it should be brought about and confirmed; he committing his ways to the Lord, his thoughts should be established, or his purposes and designs effected, see Psalm 1:3; or rather as a praying man; and so it agrees with what goes before, that he should lift up his voice to God, and pray unto him with success, and have just occasion to praise him, or pay his vows to him, since he should have the desires of his heart; whatever was upon his mind, and he prayed in faith for, he should have it; as Elijah prayed, both that it might not rain, and that it might rain, and both were according to his word, or the decree of his lips in prayer: see 1 Kings 17:1;

and the light shall shine upon thy ways; which is the reason of all things prospering and succeeding, and being established according to his wish and will; the light of grace shining in him, to put him upon and instruct him in denying and avoiding that which is sinful, and doing that which was just and good; and the light of the word without him, being a light unto his feet, and a lamp to his paths, to guide and direct him, and especially the light of God's favour and blessing on him, succeeding him in all his ways and works, and making them prosperous.
