Deuteronomy 23:14-16

New Revised Standard Version, Anglicised

¹⁴ Because the Lord your God travels along with your camp, to save you and to hand over your enemies to you, therefore your camp must be holy, so that he may not see anything indecent among you and turn away from you.

¹⁵ Slaves who have escaped to you from their owners shall not be given back to them. ¹⁶ They shall reside with you, in your midst, in any place they choose in any one of your towns, wherever they please; you shall not oppress them.
