Genesis 35:23

And Leah conceived, and bare a son, and she called his name Reuben: for she said, Surely the LORD hath looked upon my affliction; now therefore my husband will love me. And she conceived again, and bare a son; and said, Because the LORD hath heard I was hated, he hath therefore given me this son also: and she called his name Simeon. And she conceived again, and bare a son; and said, Now this time will my husband be joined unto me, because I have born him three sons: therefore was his name called Levi. And she conceived again, and bare a son: and she said, Now will I praise the LORD: therefore she called his name Judah; and left bearing.

And Leah said, God hath given me my hire, because I have given my maiden to my husband: and she called his name Issachar. And Leah conceived again, and bare Jacob the sixth son. And Leah said, God hath endued me with a good dowry; now will my husband dwell with me, because I have born him six sons: and she called his name Zebulun.

And he put the handmaids and their children foremost, and Leah and her children after, and Rachel and Joseph hindermost.

And these are the names of the children of Israel, which came into Egypt, Jacob and his sons: Reuben, Jacob's firstborn. And the sons of Reuben; Hanoch, and Phallu, and Hezron, and Carmi. And the sons of Simeon; Jemuel, and Jamin, and Ohad, and Jachin, and Zohar, and Shaul the son of a Canaanitish woman. And the sons of Levi; Gershon, Kohath, and Merari. And the sons of Judah; Er, and Onan, and Shelah, and Pharez, and Zarah: but Er and Onan died in the land of Canaan. And the sons of Pharez were Hezron and Hamul. And the sons of Issachar; Tola, and Phuvah, and Job, and Shimron. And the sons of Zebulun; Sered, and Elon, and Jahleel. These be the sons of Leah, which she bare unto Jacob in Padanaram, with his daughter Dinah: all the souls of his sons and his daughters were thirty and three.
