17:1 And all the congregation of the children of Israel journeyed from the wilderness of Sin, after their journeys, according to the commandment of the LORD, and pitched in a Rephidim: and [there was] no water for the people to drink.
(a) Moses does not note every place where they camped as in Numbers 33, but only those places where some notable thing was done. 17:2 Wherefore the people did chide with Moses, and said, Give us water that we may drink.

(h) In the book of the law. 17:15 And Moses built an altar, and called the name of it i Jehovahnissi:
