Joshua 9:14-16

Amplified Bible

¹⁴ So the men [of Israel] took some of their own provisions [and offered them in friendship], and [foolishly] did not ask for the counsel of the Lord. ¹⁵ Joshua made peace with them and made a covenant (treaty) with them, to let them live; and the leaders of the congregation [of Israel] swore an oath to them.

¹⁶ It happened that three days after they had made a covenant (treaty) with them, the Israelites heard that they were [actually] their neighbors and that they were living among them.
