But Nahash the Ammonite replied, “I will make a treaty with you on one condition, that I may put out everyone’s right eye and bring reproach upon all Israel.”
The Ammonites were bad neighbours to those tribes of Israel that lay next them, though descendants from just Lot, and, for that reason, dealt civilly with by Israel. See Deu 2:19. Jephthah, in his time, had humbled them, but now the sin of Israel had put them into a capacity to make head again, and avenge that quarrel.

In a very haughty and scornful manner: on this condition will I make a covenant with you, that I may thrust out all your right eyes; some Jewish writers go into a mystical and allegorical sense of these words, as that Nahash ordered the book of the law to be brought, which was their right eye, that he might...
thrust out all your right eyes--literally, "scoop" or "hollow out" the ball. This barbarous mutilation is the usual punishment of usurpers in the East, inflicted on chiefs; sometimes, also, even in modern history, on the whole male population of a town.
