Why dost Thou shew me iniquity, and cause me to behold - , or rather, "Why beholdest Thou grievance?" God seemed to reverse what He had said by Balaam Numbers 23:21, "He hath not beheld iniquity in Jacob, and hath not seen grievousness in Israel"; and in the Psalm Psalm 10:14, "Thou hast seen, for thou (emphatic) beholdest grievousness and wrong, to put it in Thy hand," i. e., Thou layest it up in Thy hand, to cast it back on the head of the evildoer. Now He seemed to behold it and leave it unpunished, which yet Habakkuk says to God below, He could not do Habakkuk 1:13; "Thou canst not look upon iniquity." What then did this mean? What was the solution?
All forms and shapes of sin are multiplied; oppressive "violence" , such as "covered the earth" before the flood, and brought it down; which Nineveh had to put away Jonah 3:8, and it was spared; "iniquity," i. e., what is unequal and contrary to truth, falsehood.
Grievance - literally, burdensome wearisome "toil"; "spoiling," or open robbery; "strife and contention," both through perversion of the law and, without it, through endless jarrings of man with man. Sin recoils on the sinner. So what he beholds is not "iniquity" only, but (in the same word) "vanity"; "grievance"; which is a burden both to him who suffers, and yet more to him who inflicts it. For nothing is so burdensome as sin, nothing so empty as wickedness. And while to him who suffers, the suffering is temporal, to him who inflicts it, it is eternal. And yet the prophet and whose prays against ungodliness, "must commiserate him who doth wrong yet more, since they hurt what is most precious, their own soul, and that eternally" . All then is full of evil. Wherever the prophet looks, some fresh violence is before him; it confronts him on every side; "strife hath arisen" , come up, exists where it was not before; "contention lifteth itself" on high, bowing down all beside.

And cause me to behold grievance - עמל amal, labor, toil, distress, misery, etc., the common fruits of sin.

Why dost thou show me iniquity, and cause me to behold grievance?.... That is, wicked men, and such as give a great deal of trouble vexation, and grief to others, by their rapine and oppression; suggesting that he could not turn his eyes any where, but such persons presented themselves to his view; and that their wicked actions were performed by them openly and publicly, in the sight of all, without any shame or fear. So the Targum,
"why do I see oppressors, and behold those that do the labour of falsehood?''
For spoiling and violence are before me; in my sight and presence, though a prophet, and notwithstanding all my remonstrances, exhortations, and reproofs; such were the hardness, obstinacy, and impudence of this people; to such a height and pitch of iniquity were they arrived, as to regard not the prophets of the Lord. The Targum is,
"spoilers and robbers are before me:''
or, "against me" (q), as in the text; these sins were committed against him, he was injuriously used himself; or they were done to others, contrary to his advice and persuasion:
and there are that raise up strife and contention; in the kingdom, in cities, in families; in one man, brother, friend, and neighbour, against another; which occasion lawsuits, and in them justice is not done, as follows. It may be rendered, and "there shall be and is a man of strife"; so Japhet: "and he shall raise up contention"; one man given to strife will and does use great contention in communities, civil and religious.
(q) "contra me", Pagninus, Montanus; "e regione mei", Junius & Tremellius, Piscator, Tarnovius.

cause me to behold grievance--MAURER denies that the Hebrew verb is ever active; he translates, "(Wherefore) dost Thou behold (without doing aught to check) grievance?" The context favors English Version.
there are that raise up strife and contention--so CALVIN. But MAURER, not so well, translates, "There is strife, and contention raises itself."
