Genesis 30:19-20

30:19 Leah became pregnant again and gave Jacob a son for the sixth time. ¹  30:20 Then Leah said, “God has given me a good gift. Now my husband will honor me because I have given him six sons.” So she named him Zebulun. ² 

Genesis 46:14

46:14 The sons of Zebulun:

Sered, Elon, and Jahleel.

[30:19]  ¹ tn Heb “and she bore a sixth son for Jacob,” i.e., this was the sixth son that Leah had given Jacob.

[30:20]  ² sn The name Zebulun (זְבֻלוּן, zevulun) apparently means “honor.” The name plays on the verb used in the statement made earlier in the verse. The Hebrew verb translated “will honor” and the name Zebulun derive from the same root.
