Exodus 29:30 Meaning and Commentary

Exodus 29:30

And that son that is priest in his stead
The Targum of Jonathan is,

``who shall rise after him of his sons, not of the Levites;''

for the high priest was to be of the family of Aaron, a descendant of his; it was not enough that he was of the tribe of Levi, but he must descend from Aaron, either in the line of Eleazar or of Ithamar:

shall put them on seven days;
the next successor was to wear the garments seven days running:

when he cometh into the tabernacle of the congregation to minister in
the holy place;
to offer sacrifice in the court of the tabernacle, on the altar of burnt offering, and to offer incense on the altar of incense, and to trim the lamps of the candlestick, and to put the shewbread on the table.
