Exodus 17:3

(3) To kill us.—This was no exaggeration. Thirst kills as surely as hunger, and more quickly. Whole armies have died of it. (Herod. iii. 26.) Ships’ crews have perished of it on the ocean, with “water, water everywhere, and not a drop to drink.” Unless a supply could somehow or other have been provided speedily, the whole people must have been exterminated.
