הלכה אויף יהושע 9:9

Joshua dispatched three communiqués before entering the Land. The first one he sent read, “Whoever wishes to flee, may flee”. The next read, “Whoever wishes to make peace, let him make peace”. The next read, “Whoever wishes to make war, make war”. If so, why did the residents of Givon go and deceive us³⁹Saying, “we are from a distant land” when they could have simply made peace with us (Joshua 9:9).? He had sent the (first) letter to them, and they did not accept it. Being unaware of the Laws of Israel, they thought that we won’t again be offering them peace⁴⁰After the first time, i.e., they would not have a second chance.. So, why was this matter difficult for the Heads⁴¹Of the Tribes., and they saw that it would have been proper to smite them by sword were it not for the oath⁴²That they made with the Givonites.? Because they made a treaty with them, and it says, “make no peace treaty with them” (Deut. 7:2). Thus, their verdict was that they were to be serfs. Now, since we, in error, made an oath with them, by law, they should have been killed because they deceived us, were it not for the disgrace doing so would have caused to G-d’s Name.
