Psalms 55:15

“Let death seize upon them, etc.] Ahithophel and his accomplices, Judas and the men with him; as a mighty man, as the king of terrors, and shake them to pieces. Or, “let him exact upon them” f725; as a creditor upon the debtor, and demand the debt of punishment for sin: or let him come upon them at an unawares; let them not die a natural, but a violent death. The Targum mentions Doeg and Ahithophel; [and] let them, go down quick into hell: as Korah, Dathan, and Abiram, went down quick or alive into the earth; so let these men die, and descend into the grave, in their full strength; and accordingly Absalom and Ahithophel died sudden and violent deaths, (<101723>2 Samuel 17:23 18:9); and so did…”

Injury is sometimes done in the translation of the Scriptures by the insertion of a wish or prayer, where all that is necessarily implied in the original is the statement of a fact. This has been caused here by the somewhat…”

“Them - All such as pretend to religion, and have manifestly apostatized both from the profession and practice of it. The grave - Cut off by a sudden and violent death. Among them - Heb. in their inwards. Wickedness is deeply rooted in their hearts. Psalms 55:17”

“Let death: etc. Or, rather, "Death shall seize on them; they shall descend quickly into the grave;" which is a prediction of the sudden destruction which befell the ringleaders of this unnatural rebellion.
