C. F. Keil and Franz Delitzsch on 1 Kings 4:3

1Ki 4:3 Elichoreph and Achijah, sons of Shisha, who had held the same office under David, were secretaries of state (ספרים: see at 2Sa 8:17 and 2Sa 20:25, where the different names שׁשׁא = שׁיא and שׂריה are also discussed). - Jehoshaphat the son of Ahilud was the chancellor, as he had already been in the time of David (2Sa 8:17 and 2Sa 20:24). The rendering of Thenius, “whilst Jehoshaphat was chancellor,” is grammatically impossible.
