'Usury' in the Bible

Then I consulted with myself, and contended with the nobles and the rulers, and said to them, "You exact usury, everyone of his brother." I held a great assembly against them.

I likewise, my brothers and my servants, lend them money and grain. Please let us stop this usury.

he who doesn't lend out his money for usury, nor take a bribe against the innocent. He who does these things shall never be shaken. A Poem by David.
