Exodus 17:1

²When they had departed from Rephidim, and had come to the wilderness of Sinai, they encamped in the wilderness; and there Israel encamped before the mountain.

¹They took their journey from Elim, and all the congregation of the children of Israel came to the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after their departing out of the land of Egypt.

¹²They traveled from the wilderness of Sin, and encamped in Dophkah. ¹³They traveled from Dophkah, and encamped in Alush. ¹⁴They traveled from Alush, and encamped in Rephidim, where there was no water for the people to drink.

⁸Then Amalek came and fought with Israel in Rephidim.
