John Gill's Exposition of the Whole Bible
Ezekiel 22:12
In thee have they taken gifts to shed blood..... Innocent blood, as the Targum; judges upon the bench, whose office it is to take the part of the innocent, and clear him from unjust charges; and protect him from the violence of wicked and unreasonable men; that lay things to his charge, which, if true, would require blood; and yet men in such offices took bribes to bring in the innocent guilty, and pass sentence of death on him; which is a most shocking iniquity indeed: to take bribes in pecuniary matters is very wicked; but to do it in cases which affect life is most dreadfully cruel: or if it is to be understood of such persons who take bribes to bear false witness against a man, to the taking away of his life, it is a very heinous and detestable sin; for, as for a set of jurymen bribed to bring in a wrong verdict, which would be equally a most enormous crime; such a custom to try causes to be determined by a jury did not obtain among the Jews:
thou hast taken usury and increase, and thou hast greedily gained of thy neighbours by extortion; not content with moderate usury, and increase, and even that were forbid the Jews among themselves; so greedy were they of gain at any rate, that they extorted it of their neighbours, in the most violent and oppressive manner. Kimchi, by her "friends or neighbours", understands the Assyrians and Egyptians; to whom she gave gifts, extorted by oppression from her own people, to get help of them:
and hast forgotten me, saith the Lord; to seek for help from me; or they had forgotten his law, which forbids the above sins; they had forgotten the instructions, cautions, and directions he had given them. The Targum is,
"and hast forsook my worship;''
forgetfulness of God is the cause of all sin.
