And Saul answered - thou shalt surely die, Jonathan - To save thy rash oath! So must John Baptist's head be taken off at the desire of an impure woman, because a Herod had sworn to give her whatever she might request! Unfeeling brute! However, the king was Judge. But what said the people, who were the Jury?
And Saul answered, God do so and more also,.... A form of an oath imprecating evils upon him more and greater than he chose to mention, see the like form in Ruth 1:17, though Abarbinel thinks this is not the form of an oath, but an asseveration of a curse that would befall him; as that God would not answer him when he inquired of him, and that he would add to do so again and again, if he died not:
for thou shall surely die, Jonathan; such words from a father must be very striking to a son, and argue a want of paternal affection in Saul, that could call his son by his name, and deliver such a speech unto him in so strong a manner.
For thou, &c - We have no proof, that Saul did not act in this whole affair from a real fear of God.
