19 Then Leah became pregnant again and gave birth to a sixth son for Jacob. 20 She named him Zebulun, for she said, "God has given me a good reward. Now my husband will treat me with respect, for I have given him six sons."

Matthew Henry's Commentary on Genesis 30:19-20

Commentary on Genesis 30:14-24

(Read Genesis 30:14-24)

The truth appears to be, that they were influenced by the promises of God to Abraham; whose posterity were promised the richest blessings, and from whom the Messiah was to descend.
