and after Ahithophel was Jehoiada the son of Benaiah, and Abiathar; and the captain of the king’s host was Joab.

אלא בבית דין של שבעים ואחד – as it is written (I Chronicles 27:34): “After Ahitophel were Jehoiada son of Benaiah [and Abiathar. The commander of the king’s army was Joab.” (In verse 33 is written:) “Ahitophel was a counselor to the king.” Jehoiada son of Benaiah is the Sanhedrin, for he was the greatest of them all and all of them were dragged after him. (The Bartenura or the Gemara – Sanhedrin 16b and see the Tosafot misquoted the verse).
