Deuteronomy 23:13-15

Amplified Bible

¹³ and you shall have a spade among your tools, and when you [prepare to] sit down outside [to relieve yourself], you shall dig a hole with it and shall turn and cover up your waste. ¹⁴ Since the Lord your God walks in the midst of your camp to rescue you and to defeat your enemies before you, therefore your camp must be holy (undefiled); and He must not see anything indecent among you or He will turn away from you.

¹⁵ “You shall not hand over to his master a slave who has escaped from his master to you.
