2 Samuel 8:18
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.
