(38) Keeping the charge of the sanctuary . . . --The word mikdash (sanctuary) appears to be of a more comprehensive import than mishkan, the shittimwood building, or ohel, the tent which covered it, and it seems to include the court which surrounded the Tabernacle, as in Leviticus 12:4; Leviticus 21:12.

For the charge of the children of Israel--i.e., to attend to everything which was commanded the children of Israel.

Verse 38. - Before the tabernacle toward the east,... Moses, and Aaron and his sons. The most central and honourable place in the camp, and the most convenient for constant and direct access to the sanctuary. Moses held a wholly personal and exceptional position as king in Jeshurun (Deuteronomy 33:5); Aaron was hereditary high priest. Between them they represented the union of royal and sacerdotal authority, which had many partial continuations in Jewish history, but was fully realized in Christ.

3:14-39 The Levites were in three classes, according to the sons of Levi; Gershon, Kohath, and Merari; and these were subdivided into families. The posterity of Moses were not at all honoured or privileged, but stood upon the level with other Levites; thus it was plain, that Moses did not seek the advancement of his own family, or to secure any honours to it. The tribe of Levi was by much the least of all the tribes. God's chosen are but a little flock in comparison with the world.And those that encamp before the tabernacle toward the east,.... At which was the entrance into the tabernacle:

even before the tabernacle of the congregation eastward; that is, before the court of the tabernacle, where the people assembled together:

shall be Moses, Aaron, and his sons; Moses the chief ruler, and Aaron the high priest, and his sons priests under him; these had the most honourable place of all, beings at the front of the tabernacle, between that and the camp of Judah. There is an extraordinary prick on the word Aaron, to show, as Jarchi says, that he was not in the number of Levites, though of the tribe of Levi, being high priest:

keeping the charge of the sanctuary, for the charge of the children of Israel; either in their room and stead, which otherwise they must have kept; or rather for their safety and security, keeping out all persons from entering into the sanctuary, who had no business there, that they died not, as it follows:

and the stranger that cometh nigh shall be put to death; that is, whoever came nigh to enter into the holy place, and did, who was no priest, though an Israelite, and even a Levite, or into the most holy place, excepting the high priest, it was death unto him, either by the civil magistrate, or by the hand of heaven; so the Targum of Jonathan.
