1 Samuel 11:3 - Joseph Benson’s Commentary on the Old and New Testaments

Give us seven days respite It may seem strange, either that they should propose to submit so soon to such base conditions, if they did not receive help, or that Nahash should grant them so much respite when he saw them so abject and inclined to yield to him. But the reason of both is evident; for the elders of Jabesh thought Saul was not able to help them, having not yet taken upon him the government, but living privately, 1 Samuel 11:5; and Nahash, it is probable, was loath to drive them to desperation by denying them this short space wherein to expect relief, which he thought they could not possibly obtain in the time, even if Saul should endeavour to levy an army and come to their aid, for that, he would naturally suppose, could not be done in so few days.
