Albert Barnes Commentary Ezekiel 18:8

"he that hath not given forth upon interest, neither hath taken any increase, that hath withdrawn his hand from iniquity, hath executed true justice between man and man," — Ezekiel 18:8 (ASV)

Usury - is the profit exacted for the loan of money, “increase” what is taken for goods; both are forbidden (Leviticus 25:36; Deuteronomy 23:19). The lending of capital at interest for commercial purposes is not considered here. This refers to money lent to a brother in distress.
