6:18 The descendants (literally sons) of Kohath included Amram, Izhar, Hebron, and Uzziel: The Hebrew word for “sons” can also mean “descendants,” which accommodates the possibility of unnamed generations.

And Amram took him Jochebed his father's sister to wife,.... This Amram was the first son of Kohath, and the father of Moses, as after related, and so must be the same with the man of the house of Levi, and his wife the daughter of Levi, as in Exo 2:1 and though such a marriage was afterwards prohibited, Moses does not conceal it, though it may seem to reflect some dishonour on him and his family; he writing not for his own glory, but for the sake of truth, and the good of mankind, and especially the church and people of God. Indeed the Vulgate Latin version, and the Septuagint, Samaritan, and Syriac versions, make her to be his first cousin, the daughter of his father's brother, his uncle's daughter: and so does Polyhistor from Demetrius (h); but in Num 26:59, she is expressly said to be a daughter of Levi, born to him in Egypt, and therefore must be his father's sister:

and she bare him Aaron and Moses: and Miriam also, though not mentioned, it being for the sake of these two that the genealogy is made:

and the years of the life of Amram were one hundred and thirty seven years: just the age of his grandfather Levi, Exo 6:16. A Jewish chronologer (i) says he died in the thirtieth year of Moses: but the Arabic writers (k) say in the fifty sixth or fifty seventh, and at the end of A. M. 3810. Polyhistor (l) from Demetrius makes his age to be one hundred and thirty six, and him to be the father of Moses and Aaron, and Aaron to be three years older than Moses, exactly according to the Scripture account.

The sons of Kohath. The same names are given in 1Ch_6:2 and 15. The years of the life of Kohath. Kohath, who was probably about twenty at the time of the descent into Egypt, must have considerably outlived Joseph, who died about seventy years after the descent. His eldest son, Amram, is not likely to have been born much later than his father"s thirtieth year. (see Gen_11:12-24) Amram would thus have been contemporary with Joseph for above fifty years.

ושני חיי קהת … ושני חיי עמרם וגו׳ AND THE YEARS OF THE LIFE OF KOHATH WERE etc. … AND THE YEARS OF THE LIFE OF AMRAM WERE etc. — From these numbers we may gather regarding the period of residence of the children of Israel, — viz., four hundred years, of which Scripture speaks, that these four hundred years were not passed in Egypt alone, but that they date from the day of Isaac’s birth. You know that Kohath was one of those who went down to Egypt; now reckon all his years (133) although really we should not take into account the years he lived before he went down to Egypt, and the years of Amram, his son (137), and the eighty years of Moses, the latter’s son, which he had attained when the Israelites left Egypt, and you will not find them totaling to four hundred, and in this calculation many years of the sons’ ages are included in those of their fathers (i. e. in such a calculation one must deduct in each instance the father’s age when his son was born since this number is included in the total age of each of these persons) (cf. Rashi on Exodus 12:40)
