Deuteronomy 15:5-7

5But you must always obey him completely. So be careful to obey all the commands that I am giving to you today.

6For the Lord your God will bless you, as he has promised to do. You will lend money to the people of many other nations, but you will not borrow money from them. You will rule over many other nations, but they will not rule over you.

7The Lord your God will bless you in the land that he is giving to you. But perhaps there will be a poor person among the Israelites in one of your towns. Then do not refuse to help him. Do not think only about yourself.
