Sarah means princess, and God renamed her for it: thou shalt not call her name Sarai, but Sarah shall her name be... and she shall be a mother of nations; kings of people shall be of her. Barren into old age, she laughed at the promise of a son — and then bore Isaac, whose name means laughter.
The New Testament honours her as a model of faith and a mother of the faithful; Peter points to her quiet, trusting spirit. Her long life spans doubt, laughter, and a promise kept against all odds.
Sarah has been one of the most beloved girls' names for generations — graceful, timeless, and warmly shortened to Sadie.
Sara, Sadie, Sarai, Zara
Sarah in the Bible
And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be.
