"This is what we will do to them: let them live, so that wrath does not fall upon us on account of the oath we swore to them."
This we will do to them; we will even let them live, lest wrath be upon us, because of the oath which we sware unto them.
This is how we will treat them: We will let them live, so that no wrath will fall on us because of the oath we swore to them.”
