The sons of Bilhah, Rachel's handmaid, come last. Hushim, the son of Dan, appears in Numbers Num 26:42 as Shuham, and perhaps in Chronicles 1 Chronicles 7:12 in an obscure connection. The four sons of Naphtali occur in all the lists, Shallum being the variant in Chronicles 1 Chronicles 7:13 for Shillem. The descendants of Bilhah are seven - two sons and five grandsons.

And the sons of Dan, Hushim. He had but one son, wherefore the plural is put for the singular, see Genesis 46:7; Aben Ezra thinks he had two sons, and that one of them was dead, and therefore not mentioned; but the other way best accounts for the expression; though, as Schmidt observes, the plural may be indefinitely put, and the sense be this, as for the sons of Dan, there was only one, whose name was Hushim. Dan was a son of Jacob by Bilhah, Rachel's maid, as the following was another.

And the sons of Dan; Hushim.

46:5-27 We have here a particular account of Jacob's family. Though the fulfilling of promises is always sure, yet it is often slow.
