He that hath not given forth upon usury, neither hath taken any increase, that hath withdrawn his hand from iniquity, hath executed true judgment between man and man,

Wesley's Notes

18:8 Increase - Illegal interest. Iniquity - Injustice of every kind.

Jamieson-Fausset-Brown Bible Commentary

8. usury-literally, "biting." The law forbade the Jew to take interest from brethren but permitted him to do so from a foreigner (Ex 22:25; De 23:19, 20; Ne 5:7; Ps 15:5). The letter of the law was restricted to the Jewish polity, and is not binding now; and indeed the principle of taking interest was even then sanctioned, by its being allowed in the case of a foreigner. The spirit of the law still binds us, that we are not to take advantage of our neighbor's necessities to enrich ourselves, but be satisfied with moderate, or even no, interest, in the case of the needy.

increase-in the case of other kinds of wealth; as "usury" refers to money (Le 25:36).

withdrawn . hand, &c.-Where he has the opportunity and might find a plausible plea for promoting his own gain at the cost of a wrong to his neighbor, he keeps back his hand from what selfishness prompts.

judgment-justice.

Matthew Henry's Concise Commentary

18:1-20 The soul that sinneth it shall die. As to eternity, every man was, is, and will be dealt with, as his conduct shows him to have been under the old covenant of works, or the new covenant of grace. Whatever outward sufferings come upon men through the sins of others, they deserve for their own sins all they suffer; and the Lord overrules every event for the eternal good of believers. All souls are in the hand of the great Creator: he will deal with them in justice or mercy; nor will any perish for the sins of another, who is not in some sense worthy of death for his own. We all have sinned, and our souls must be lost, if God deal with us according to his holy law; but we are invited to come to Christ. If a man who had shown his faith by his works, had a wicked son, whose character and conduct were the reverse of his parent's, could it be expected he should escape the Divine vengeance on account of his father's piety? Surely not. And should a wicked man have a son who walked before God as righteous, this man would not perish for his father's sins. If the son was not free from evils in this life, still he should be partaker of salvation. The question here is not about the meritorious ground of justification, but about the Lord's dealings with the righteous and the wicked.
