Chronicles I 26:32 Meaning and Commentary

1 Chronicles 26:32

And his brethren, men of valour, were two thousand and seven
hundred chief fathers
That is, the brethren or kinsmen of Jerijah the Hebronite were so many principal men in their families, and men of fortitude and courage:

whom King David made rulers over the Reubenites, the Gadites, and the
half tribe of Manasseh;
all which lay on the other side Jordan; and being so remote from the seat of civil government, and of the worship of God, they were in greater danger of revolting, both from their obedience to their king, and duty to their God; land therefore so large a number was appointed over them, to instruct them and keep them in their duty to both, as follows:

for every matter pertaining to God, and affairs of the king;
to see that they kept close to the pure worship and service of God; and were faithful and loyal subjects of the king.
