Deuteronomy 15:9

15:9 Be careful lest you entertain the wicked thought that the seventh year, the year of cancellation of debts, has almost arrived, and your attitude be wrong toward your impoverished fellow Israelite and you do not lend him anything; he will cry out to the Lord against you and you will be regarded as having sinned.

Deuteronomy 23:14

23:14 For the Lord your God walks about in the middle of your camp to deliver you and defeat your enemies for you. Therefore your camp should be holy, so that he does not see anything indecent among you and turn away from you.
