Matthew Poole and continuators on 1 Chronicles 26:29

29 Of the Izharite, Chenaniah and his sons were for the outward business over Israel , for officers and Judges .

Who are probably thought to have been 1600, for that Sum added to the 1700, v. 30. and the 2700, v. 32. make up those 6000 Levites which were Officers and Iudges, 1 Chron. 23. 4.

For that business of the Lord and of the King (as it is explained here, v. 30, 32.) which was to be done without the Temple and without Ierusalem; for what was to be done within them was committed to other hands, as we have seen.

Synecdochically, i. e. over part of Israel, even over the Midland part and that which lay upon the Sea Coast: for the other parts of the Land on both sides of Iord[illegible: 1+ letters]n are here committed to others, v. [illegible: 1+ letters]0, 31, 32.

Who shall be Officers and Judges over the People in the several Cities and Towns or Parts of the Land to determine Questions and Controversies which might arise among them. And the reason why the Levites were instrusted with these Matters was, because the Common or Municipal Law of Israel, by which they had and held all their Rights, was no other than the Law of God, whereof the Priests and Levites being the best and established Interpreters, must needs therefore be the most proper Judges of things depending thereupon.
