C. F. Keil and Franz Delitzsch on Exodus 1:2-5

Exo 1:1-5

To place the multiplication of the children of Israel into a strong nation in its true light, as the commencement of the realization of the promises of God, the number of the souls that went down with Jacob to Egypt is repeated from Gen 46:27 (on the number 70, in which Jacob is included, see the notes on this passage); and the repetition of the names of the twelve sons of Jacob serves to give to the history which follows a character of completeness within itself. “With Jacob they came, every one and his house,” i.e., his sons, together with their families, their wives, and their children. The sons are arranged according to their mothers, as in Gen 35:23-26, and the sons of the two maid-servants stand last. Joseph, indeed, is not placed in the list, but brought into special prominence by the words, “for Joseph was in Egypt” (Exo 1:5), since he did not go down to Egypt along with the house of Jacob, and occupied an exalted position in relation to them there.
