John Gill Commentary Numbers 33:14

"And they journeyed from Alush, and encamped in Rephidim, where was no water for the people to drink." — Numbers 33:14 (ASV)

And they removed from Alush, and encamped at Rephidim
Eight miles from Alush:

where was no water for the people to drink ;
and they murmured, and a rock here was smitten by Moses at the command of God, and waters gushed out sufficient for them and their flocks, (Exodus 17:1–16) .
