Genesis 30:18-21

30:18 Then Leah said, “God has granted me a reward because I gave my servant to my husband as a wife.” So she named him Issachar.

30:19 Leah became pregnant again and gave Jacob a son for the sixth time. 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.

30:21 After that she gave birth to a daughter and named her Dinah.
