Exodus 15:27; Exodus 16:1

27 And they came to Elim, where were twelve wells of water, and threescore and ten palm trees: and they encamped there by the waters.

1 And they took their journey from Elim, and all the congregation of the children of Israel came unto 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.
