The whole Israelite community set out from Elim, and on the fifteenth day of the second month after they had left Egypt, they came to the desert of Sin, which is between Elim and Sinai.

Then they camped at Dophkah,

Next was Rephidim, where there was no water for them to drink.

The Amalekites came and attacked the Israelites at Rephidim.
