About Ahitub 1 ., High Priest
The grandfather of Zadok, and son of Meraioth, high priest in David's reign.-- Everyone in the Bible by William P. Barker.
1 Chronicles 6, The sons of Levi, including David's singers, are listed -- Office of Aaron, and his line is given -- Levite cities designated in the areas of the various tribes........
In the list of David's ministers in Samuel B, 8,14: "and Zadok ben Ahihud and Ahimelech ben Abiatar - priests", the order of the names Zadok ben Ahitub is probably wrong. The Bible scholar Shimon Bar-Efrat argues that the correct way to read it is: "Zadok and Ebiatar ben Ahimelech ben Ahitub - priests".
