Genesis 30:20

“And Leah said, God hath endued me [with] a good dowry, etc.] Having so many children; for though her husband could give her nothing at marriage, and her father gave her no more than one handmaid, yet God had abundantly made it up to her, in giving her so many sons: these are the heritage of the Lord, (<19C703>Psalm 127:3); now will my husband dwell with me; constantly; and not come to her tent now and then only, as he had used to do; because I have borne him six sons; this she thought would fix his affections to her, and cause him to cleave to her, and continue with her: and she called his name Zebulun; which signifies “dwelling”. These two sons of Leah, according to the Jewish writers…”

“And Leah said, God hath endued me with a good dowry--The birth of a son is hailed with demonstrations of joy, and the possession of several sons confers upon the mother an honor and respectability proportioned to their number. The husband attaches a similar importance to the possession, and it forms a bond of union which renders it impossible for him ever to forsake or to be cold to a wife who has borne him sons. This explains the happy anticipations Leah founded on the possession of her six sons.”
