Origen, on Josh 11:1

“And when Jabin king of Asor had heard these things, he sent to Jobab king of Madon, and to the king of Semeron, and to the king of Achsaph:”

“This one sends word to Jobab; for he himself is the one who sends word to all nations and summons them to battle. He sends word to the king of Merom. Jobab means "hostilities," but Merom means "bitternesses." Therefore, the devil sends word to another hostile power, doubtless from among the fugitive angels, and this power is the king of bitternesses. All bitternesses and difficulties in this world that are inflicted on wretched mortals issue from this author and what he does. There are diverse kinds of sin. For nothing can be more bitter than sin, even if it seems somewhat delightful at first, as Solomon writes. "But in the end," he says, "you will find what seemed sweet in the beginning to be more bitter than gall and sharper than the edge of a sword." But the nature of righteousness is the opposite: In the beginning, it seems more bitter, but in the end, when it produces fruits of virtue, it is found to be sweeter than honey. Therefore, the devil sent word to the hostile Jobab, the king of bitterness.”
