Genesis 46:25

These [are] the sons of Bilhah, which Laban gave unto Rachel
his daughter
To be her maid, when she was married to Jacob: and she bare these unto Jacob, all the souls [were] seven;
not that she bare seven sons to Jacob, she bore but two, Dan and Naphtali; but the children of these with them made seven, one of Dan's, and four of Naphtali's, who went down with Jacob into Egypt.
