Deuteronomy 7:2-5 And when the Lord has given them up into your hands and you have overcome them, give them up to complete destruction: make no agreement with them, and have no mercy on them:

BBE⁽ⁱ⁾ ² And when the Lord has given them up into your hands and you have overcome them, give them up to complete destruction: make no agreement with them, and have no mercy on them: ³ Do not take wives or husbands from among them; do not give your daughters to their sons, or take their daughters for your sons. ⁴ For through them your sons will be turned from me to the worship of other gods: and the Lord will be moved to wrath against you and send destruction on you quickly. ⁵ But this is what you are to do to them: their altars are to be pulled down and their pillars broken, and their holy trees cut down and their images burned with fire.
