Exodus 6:16

And these are the names of the sons of Levi, according to
their generations
Whose sons, according to the order of their birth, were as follow:

Gershom, and Kohath, and Merari;
see ( Genesis 46:11 ) :

and the years of the life of Levi were one hundred and thirty seven
years;
and exactly the same number of years is assigned him by Polyhistor from Demetrius ^F3, an Heathen writer. Jarchi says, that the reason why, the years of the life of Levi are reckoned is to show how long the bondage lasted; for there was no servitude as long as any of the tribes (or of the sons of Jacob) remained, according to ( Exodus 1:6 Exodus 1:8 ) and the Jewish chronologers ^F4 affirm that Levi was the last of the patriarchs that died; and that he died in the year of the world 3332, and lived in Egypt ninety four years; and from his time, to the going out of Egypt, were only one hundred and sixteen years; and they further say the bondage could not last longer than one hundred and sixteen years, nor shorter than eighty seven. Bishop Usher ^F5 places his death in A. M. 2385, and before Christ 1619: according to the Targum of Jonathan, he lived to see Moses and Aaron the deliverers of Israel; but that is false, since Joseph and all his brethren died before Moses was born, ( Exodus 1:6 ) .
