What does the Bible say about usury and unjust gain?

Proverbs 28:8 warns that those who increase their wealth through usury and unjust gain will ultimately gather it for those who pity the poor. This principle is reinforced by the Mosaic Law in Exodus 22:25 and Leviticus 25, where God instructs His people to lend generously to the poor without expecting profit. Such practices reflect the character of God, who desires mercy rather than sacrifice. In the context of the gospel, usury serves as a metaphor for exploitation, contrasting with the generosity God calls His people to demonstrate in their dealings with others.
