Genesis 34
21 `These men are peaceable with us; then let them dwell in the land, and trade `in' it; and the land, lo, `is' wide before them; their daughters let us take to ourselves for wives, and our daughters give to them.
22 `Only for this do the men consent to us, to dwell with us, to become one people, in every male of us being circumcised, as they are circumcised;
23 Ref their cattle, and their substance, and all their beasts -- are they not ours? only let us consent to them, and they dwell with us.'
