C. F. Keil and Franz Delitzsch on 1 Samuel 14:8-10

1Sa 14:8-10

“Behold, we go over to the people and show ourselves to them. If they say to us, Wait (דּמּוּ, keep quiet) till we come to you, we will stand still in our place, and not go up to them; but if they say thus, Come up unto us, then we will go up, for Jehovah hath (in that case) delivered them into our hand.” The sign was well chosen. If the Philistines said, “Wait till we come,” they would show some courage; but if they said, “Come up to us,” it would be a sign that they were cowardly, and had not courage enough to leave their position and attack the Hebrews. It was not tempting God for Jonathan to fix upon such a sign by which to determine the success of his enterprise; for he did it in the exercise of his calling, when fighting not for personal objects, but for the kingdom of God, which the uncircumcised were threatening to annihilate, and in the most confident belief that the Lord would deliver and preserve His people. Such faith as this God would not put to shame.
