Joshua 9:16-21

16But it came about at the end of three days after they had cut a covenant with them, they heard that they were their neighbors, and were living among them.

17So Bnei-Yisrael journeyed and came to their cities on the third day. Now their cities were Gibeon, Chephirah, Beeroth, and Kiriath-jearim.

18But Bnei-Yisrael did not strike them, because the leaders of the community had sworn to them by Adonai, God of Israel. Then the entire community murmured against the leaders,

19but all the leaders answered the entire community, “We have sworn to them by Adonai, God of Israel, so now we cannot touch them.

20This is what we will do to them: We will let them live, lest wrath be upon us because of the oath which we swore to them.”

21“Yes, let them live,” the leaders said further, “but let them chop wood and draw water for the entire community.” So the leaders decreed concerning them.
