Joshua 9:18-20

Young's Literal Translation

¹⁸ and the sons of Israel have not smitten them, for sworn to them have the princes of the company by Jehovah God of Israel, and all the company murmur against the princes.

¹⁹ And all the princes say unto all the company, `We -- we have sworn to them by Jehovah, God of Israel; and now, we are not able to come against them;

²⁰ this we do to them, and have kept them alive, and wrath is not upon us, because of the oath which we have sworn to them.'
