Genesi 17:15

And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah [shall] her name [be].

Ver. 15. Thou shalt not call her name Sarai, but Sarah.] The Chaldee, Sarai, is made Hebrew, Sarah: One of the four letters of Jehovah being also added (as before in Abraham), that she may be, absolutely, a lady or princess.
