Hephzibah (חֶפְצִי בָהּ) is a Hebrew phrase meaning "my delight is in her." Mentioned in 2 Kings 21:1 as the mother of King Manasseh; the name also appears in Isaiah 62:4 as a poetic name for restored Jerusalem.
Hephzibah is widely used in religious Christian and Jewish families.
Hephzibah 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 Hephzibah reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
