Adam Clarke on Proverbs 29:13

The poor and the deceitful man - It is difficult to fix the meaning of תככים techachim, which we here render the deceitful man. The Targum has, "The poor and the man of Little Wealth." The Septuagint, "The usurer and the Debtor." The Vulgate, "The poor and Creditor." Coverdale, "The poor and the Lender." Others, "The poor and the Rich;" "The poor and the Oppressors." I suppose the meaning may be the same as in Pro 22:2 (note): "The rich and the poor meet together; the Lord is the Maker of them all." Where see the note.
