Genesis 17:15

Then God said to Abraham, “As for your wife, you must no longer call her Sarai; ¹  Sarah ²  will be her name.

Ge 17:5; Ge 32:28; 2Sa 12:25

¹ tn Heb “[As for] Sarai your wife, you must not call her name Sarai, for Sarah [will be] her name.”

² sn Sarah. The name change seems to be a dialectical variation, both spellings meaning “princess” or “queen.” Like the name Abram, the name Sarai symbolized the past. The new name Sarah, like the name Abraham, would be a reminder of what God intended to do for Sarah in the future.
