Genesis 30:9

And Lea saw that she ceased from bearing, and she took Zelpha her maid, and gave her to Jacob for a wife; and he went in to her.

When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife.

When Leah saw that she had finished bearing, she took Zilpah, her servant, and gave her to Jacob as a wife.
