Matthew Poole and continuators on 1 Chronicles 26:6

6 Also unto Shemajah his son were two sons born, that ruled throughout the house of their fathers : for they were mighty men of valour .

That had the Command of their Brethren and Families, being, as some say, Captains of Hundreds or of Thousands: Of which see Exod. 18. 25. 2 King. 11. 9.

This Clause is divers times mentioned, because their Office required both Strength and Courage: for they were to shut the Doors of the Temple, one whereof was so great and weighty that in the second Temple it required the help of twenty men to open and shut it, as Iosephus an Eye-witness reports. They were also to keep the Guard, and to keep out all unclean or forbidden Persons who might sometimes presumptuously attempt to enter into the Temple, as Uzziah did, and to prevent or suppress any Tumults or Disorders which might happen in the Temple or in its Courts, and to keep the Treasures of the Temple, v. 20, 22, 24, 26. and to be officers and judges over Israel, v. 29. and to manage every matter pertaining to God and the affairs of the King, [illegible: 1+ letters]. 32.
