1 Chronicles 18:16
And Zadok the son of Ahitub, and Abimelech the son of Abiathar, were the priests; and Shavsha was scribe; (1 Chronicles 18:16)
Zadok.
 For Zadok, of the line of Eleazar (ch. 6:4-8), see on 2 Sam. 8:17.
Abimelech.
 This should be spelled Ahimelech as in 2 Sam. 8:17. An Ahimelech is mentioned both as the father of Abiathar (1 Sam. 22:20) and as the son (1 Chron. 24:6). Elsewhere Zadok and Abiathar are named as the priests (see 2 Sam. 15:29, 35). On the harmony of these statements see on 2 Sam. 8:17.
