Genesis 30:8-9

And Rachel said, With great wrestlings have I wrestled with my sister, and I have prevailed: and she called his name Naphtali. {great...: Heb. wrestlings of God} {Naphtali: that is, My wrestling: Gr. Nephthalim} When Leah saw that she had left bearing, she took Zilpah her maid, and gave her Jacob to wife.
