Deuteronomy 20:15

Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.

Thus shall you do to all the cities which are very far off from you, which are not of the cities of these nations.

Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.

So thou dost do to all the cities which are very far off from thee, which are not of the cities of these nations.

This is how you are to treat all the cities that are far away from you and do not belong to the nations nearby.
