2 Samuel 8:18

8:18 Benaiah son of Jehoida supervised ¹  the Kerithites and Pelethites; and David’s sons were priests. ² 

1 Raja-raja 1:38

1:38 So Zadok the priest, Nathan the prophet, Benaiah son of Jehoiada, the Kerethites, and the Pelethites ³  went down, put Solomon on King David’s mule, and led him to Gihon.

[8:18]  ¹ tc The translation follows the Syriac Peshitta, Targum, and Vulgate in reading “over,” rather than the simple conjunction that appears in MT. See also the parallel passage in 1 Chr 18:17.

[8:18]  ² sn That David’s sons could have been priests, in light of the fact that they were not of the priestly lineage, is strange. One must assume either (1) that the word “priest” (כֹּהֵן, kohen) during this period of time could be used in a broader sense of “chief ruler” (KJV); “chief minister” (ASV, NASB), or “royal adviser” (NIV), perhaps based on the parallel passage in 1 Chr 18:17 which has “the king’s leading officials”, or (2) that in David’s day members of the king’s family could function as a special category of “priests” (cf. NLT “priestly leaders”). The latter option seems to be the more straightforward way of understanding the word in 2 Sam 8:18.

[1:38]  ³ sn The Kerethites and Pelethites were members of David’s royal guard (see 2 Sam 8:18). The Kerethites may have been descendants of an ethnic group originating in Crete.
