I thought Jacob had 13 children, being Benjamin the last one. By
- Leah: Reuben, Simeon, Levi, Judah, Essachar, Zebulun and Dinah
- Rachel: Joseph and Benjamin
- Bilhah: Dan and Naphtali
- Zilpah: Gad and Asher
which makes a total of 13.
Yet, from this answer in Quora
Yes, the Bible does indicate that Jacob had more than one daughter. However, it is instructive to note that only Dinah is mentioned (Genesis 30:19–21; 34:1–3; 46:15) .
which references passages that point to Jacob having "daughters" (plural, more than one) such as Genesis 37:34-35
34 So Jacob tore his clothes, and put on a sackcloth undergarment over his waist, and mourned for his son many days. 35 Then all his sons and all his daughters got up to comfort him, but he refused to be comforted. And he said, “Surely I will go down to Sheol in mourning for my son.” So his father wept for him.
5 Then Jacob left Beersheba, and the sons of Israel carried their father Jacob and their little ones and their wives in the wagons which Pharaoh had sent to carry him. 6 They also took their livestock and their possessions, which they had acquired in the land of Canaan, and came to Egypt, Jacob and all his descendants with him: 7 his sons and his grandsons with him, his daughters and his granddaughters, and all his descendants he brought with him to Egypt.
and then in Genesis 46:15
These are the sons of Leah, whom she bore to Jacob in Paddan-aram, with his daughter Dinah; all his sons and his daughters numbered thirty-three.
