So they and their children had the oversight of the gates of the house of the Lord,.... They that were appointed in David's time to watch the gates of the temple, their posterity succeeded them in that office; for it was hereditary:

namely, the house of the tabernacle, by wards; that which was at Gibeon in David's time, and now one was erected until the temple was built.

They (those ordained by David) and their sons (descendants) were at the doors of the house of Jahve-of the tent-house (האהל בּית is added to בּית־יהוה, in order that the latter might not be confined to Solomon's temple); for the watch (משׁמרות of persons, as in Nehemiah 12:9; Nehemiah 4:3, Nehemiah 4:16), according to the four winds (quarters) were they, i.e., the doorkeepers stood so, in accordance with the arrangement made by David; cf. 1 Chronicles 26:14.

So they and their children had the oversight of the gates of the house of the LORD, namely, the house of the tabernacle, by wards.

9:23 The oversight - Namely, in David's time. Tabernacle - This is added to explain what he means by the house of the Lord, not that tabernacle which David had set up for the ark; but that more solemn tabernacle, which Moses had made by God's express command; which in David's time was at Gibeon; in which God was worshipped until the temple was built. Wards - By turns or courses.

9:1-44 Genealogies. - This chapter expresses that one end of recording all these genealogies was, to direct the Jews, when they returned out of captivity, with whom to unite, and where to reside. Here is an account of the good state into which the affairs of religion were put, on the return from Babylon. Every one knew his charge. Work is likely to be done well when every one knows the duty of his place, and makes a business of it. God is the God of order. Thus was the temple a figure of the heavenly one, where they rest not day nor night from praising God, Re 4:8. Blessed be His name, believers there shall, not in turn, but all together, without interruption, praise him night and day: may the Lord make each of us fit for the inheritance of the saints in light.
