Even jesus raged against high interest rates.

Exodus 22:25 – “If you lend money to any of my people with you who is poor, you shall not be like a moneylender to him, and you shall not exact interest from him.”

Leviticus 25:35-37 – “If your brother becomes poor and cannot maintain himself with you, you shall support him as though he were a stranger and a sojourner, and he shall live with you. Take no interest from him or profit, but fear your God that your brother may live beside you. You shall not lend him your money at interest nor give him your food for profit.”

Psalm 15:5 – “Who lends money to the poor without interest; who does not accept a bribe against the innocent. Whoever does these things will never be shaken.”
