The people said to Saul, Shall Jonathan die, who has worked this great salvation in Israel? Far from it: as Yahweh lives, there shall not one hair of his head fall to the ground; for he has worked with God this day. So the people rescued Jonathan, that he didn't die.
The writer pointed out the reason for Saul’s ultimate failure as Israel’s king and the reason for his own personal destruction in this section (1 Samuel 13:1 to 1 Samuel 14:46). Essentially Saul refused to put the will of God above his own personal desires. Careful attention to the text shows that Saul showed great concern about the observance of religious rituals, but he failed to appreciate the indispensable importance of submitting his will to Yahweh. He sought to use God rather than allowing God to use him. He thought he was above the Mosaic Law rather than under it. He put himself in the position that God alone rightfully occupied.
