Zilpah (זִלְפָּה) is a Hebrew name of uncertain meaning. In the Book of Genesis, Zilpah was the handmaid of Leah and the mother of Jacob's sons Gad and Asher — two of the tribes of Israel.
Zilpah is widely used in religious Christian and Jewish families.
Zilpah does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Zilpah reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
