Genesis 35:18 records Benjamin's birth right before this verse — together they complete the tally of Jacob's twelve sons.

These verses are the birth narrative for Gad and Asher — Zilpah bearing them through Leah's arrangement. Genesis 35:26 simply catalogues what these verses describe.

Genesis 30:11 records Gad's birth to Zilpah — the specific event behind this line in the catalogue.

Genesis 30:13 records Asher's birth to Zilpah — the second son referenced in this catalogue entry.

In Genesis 28:2, Isaac sends Jacob to Padan-aram for a wife — the place where all these sons were eventually born.

In Genesis 46:16-18, the same Zilpah sons appear in Jacob's family list heading to Egypt — a later inventory of the same family unit.

In Genesis 46:17, these same sons of Jacob are listed again as part of his household moving to Egypt, reinforcing the family's continuity.

In Exodus 1:4, the sons of Jacob are enumerated by name again, connecting to this earlier birth record.

In 1 Chronicles 2:2, the sons of Israel (Jacob) are listed, echoing this genealogical record for Israel's tribes.
