TSK · Genesis 29:24

¶ Now Sarai Abram's wife bare him no children: and she had an handmaid, an Egyptian, whose name [was] Hagar.

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

These [are] the sons of Zilpah, whom Laban gave to Leah his daughter, and these she bare unto Jacob, [even] sixteen souls.
