Verse 2. - The second son, Kohath, rather Kehath (קְהָת, Hebrew, and so Septuagint and Vulgate), is at once singled out, in order to get at the priest line. He was one of the travellers with Jacob into Egypt, was probably about twenty years the junior of Joseph, lived thirty years after his death, and attained the age of one hundred and thirty-three years, after a residence in Egypt of about one hundred and fifteen years in all. The Kohathites are expressly mentioned in their sacred duties in the time of David (1 Chronicles 15:5-8), and in the time of Hezekiah (2 Chronicles 29:12-14). The four sons of Kohath are next instanced, in order to get another step nearer the clear beginning of the priest line. This is done in the person of the oldest brother, Amram, who became father of Aaron and Moses and Miriam.

6:1-81 Genealogies. - We have an account of Levi in this chapter. The priests and Levites were more concerned than any other Israelites, to preserve their descent clear, and to be able to prove it; because all the honours and privileges of their office depended upon their descent. Now, the Spirit of God calls ministers to their work, without any limit as to the families they came from; and then, as now, though believers and ministers may be very useful to the church, none but our great High Priest can make atonement for sin, nor can any be accepted but through his atonement.And the sons of Kohath; Amram, Izhar, and Hebron, and Uzziel,.... Given in the same order as in Exodus 6:18; see Gill on Exodus 6:18.
