Sela is from the Hebrew Selah (rock, mountain) — also from the Tongan name meaning princess. Sela in the Hebrew Bible — the iconic mountain fortress of Edom mentioned in 2 Kings 14:7 (later called Petra by the Greeks); the ancient Nabataean rock-cut city of Petra, Jordan is a UNESCO World Heritage Site (1985) and one of the New Seven Wonders of the World (2007). Sela Apera (born 1996) — Tongan rugby player. Princess Sela — modern Tongan royal heritage naming. Sela Sampson — modern American figure. Sela Vave — American singer.
Sela 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 Sela reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
