If Saul, in his zeal for Israel and Judah, attempted to kill the Gibeonites — with whom Joshua the son of Nun and all the people had made covenants — and on account of this seven of Saul's descendants, those born from his daughters, were killed, why is it that not the tribes, who were at fault, but those who had done no wrong, paid the penalty? For this is unjust. Unless, perhaps, someone should say that Saul, being king, was unable to withstand the Israelites and the tribe of Judah, and to break the fathers' covenants with the Gibeonites. But I would add to these considerations that it was God's dispensation that the whole family of Saul should be consumed — all that was ever suspected of laying claim to the royal dignity, and on account of this of rising up against David and against his children. And the "the Gibeonites exposed them to the sun before the Lord on the mountain" stands instead of saying that they did not bury the slain, but left them to lie under the sun. "And they were dissolved," it says, "and Dan the son of Joah, of the descendants of the giants, took them." It surely means to say that the giant, taking those who had been placed under the sun, carried off those who had already been dissolved by the sun's flame.
The account concerning the Gibeonites remains obscure, unless perhaps we should say that, when he sat at Gibeah to make war, Saul both routed the foreigners and destroyed, along with them, the Gibeonites also. And the narrative is in the thirty-second and thirty-third section, and the thirty-seventh, of the First book of Kingdoms, where it says, "And he warred round about against all his enemies," and what follows. And what the text says is this: Saul did wrong against him, and from his house came the avenging of the wrong done against Joshua.
But those who obtained their being from that one are not wronged in being taken away together with the one who was at the beginning. For from the source whence they had their being, from there also they have their non-being; but if they were worthy of any good thing for their own sake, they receive this later.
