Contradiction with Exodus 15:27
Exodus 15:27 describes the Israelites coming to Elim where there were twelve wells of water and seventy palm trees; whereas, Numbers 33:10 simply refers to them encamping by the Red Sea, with no mention of the abundance found in Elim, suggesting different locations or aspects of the journey.
Exodus 15:27: And they came to Elim, where [were] twelve wells of water, and threescore and ten palm trees: and they encamped there by the waters.
