'Treaty' in the Bible

Nahash the Ammonite came up and laid siege to Jabesh-gilead. All the men of Jabesh said to him, “Make a treaty with us, and we will serve you.”

But Nahash the Ammonite said to them, "The only way I will make a treaty with you is if you let me gouge out the right eye of every one of you and in so doing humiliate all Israel!"

that all of you have conspired against me, and there is none who discloses to me when my son makes a treaty with the son of Jesse, and there is none of you who is sorry for me, or discloses to me that my son has stirred up my servant against me, to lie in wait, as at this day?"
