These are the generations of Jacob. Joseph, being seventeen years old, was feeding the flock with his brethren; and the lad was with the sons of Bilhah, and with the sons of Zilpah, his father's wives: and Joseph brought unto his father their evil report.
And she gave him Bilhah her handmaid to wife: and Jacob went in unto her. ... When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife.
And it came to pass, when Israel dwelt in that land, that Reuben went and lay with Bilhah his father's concubine: and Israel heard it. Now the sons of Jacob were twelve: ... And the sons of Bilhah, Rachel's handmaid; Dan, and Naphtali: And the sons of Zilpah, Leah's handmaid; Gad, and Asher: these are the sons of Jacob, which were born to him in Padanaram.
Now Eli was very old, and heard all that his sons did unto all Israel; and how they lay with the women that assembled at the door of the tabernacle of the congregation. And he said unto them, Why do ye such things? for I hear of your evil dealings by all this people. Nay, my sons; for it is no good report that I hear: ye make the LORD's people to transgress.
It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife.
