Genesis 48:7

Rachel died by me. — Heb., died upon me, or as we should say, “died in my arms.” The mention of Rachel is to account for an act so authoritative as the bestowal of the double portion of the firstborn upon Joseph. Jacob grounds the justification of his act, not upon her being the chief wife, but upon her untimely death, which prevented her bearing other sons. Even now Leah, if we count Levi, had six tribes, each handmaid two, and Rachel three.

The same is Beth-lehem. — A note added subsequently, when the place was famous as the birthplace of David. It would not be called Beth-lehem until corn was cultivated there.
