The Prophet tells us by the way that the trench was made by King Asa, when he fortified the city against the attack of Baasha, as it is related in the sixteenth chapter of Second Chronicles. For Baasha, having collected an army, made an attack on the land of Judah and began to build the city, that he might thus keep the Jews as it were besieged, and make thence daily incursions, and where he might safely take his forces together with the spoils. Asa then hired the king of Syria, and induced him to break the treaty which the two kings of Syria and Israel had made with one another. Thus Baasha was forced to leave the work unfinished, and thence Asa is said to have carried away the gathered stones, that thereby the trench might be formed. There is indeed no mention of the trench; but we may conclude that it was then formed, in order that it might interpose between the enemy and the city. But it may seem strange that the trench was in the midst of the city, except perhaps that Asa built a fortress within the town, that if he was overcome by his enemy, he might take refuge there with his men of war, as we know that citadels are often built in the middle of cities as fortresses, as places of refuge. Asa then built this trench, that should the king of Israel take the city, he might not penetrate farther, but be kept back by the interposing trench. But only in things uncertain are conjectures to be allowed.

But the Prophet increases the indignity of the deed, when he says, that the trench was filled with the slain. It was formed for a very different end and purpose, even that the king of Judah, when reduced to the greatest straits, might have the trench as a defense against the violence of his enemies, so that he might protect his kingdom and his subjects. But now the slain were cast into the trench, not the Syrians nor the Israelites, but Jews themselves and God's pious worshipers. What then had been made for the public benefit of the people, was made by Ishmael a place for the slaughter of good men. And hence, as it has been said, the atrocity of the deed was more enhanced.
