Exodus 34:
Luke 4:
Fasting for 40 days without food is not uncommon.
Could we safely assume that Jesus had water to drink?
If it was a supernatural fast, then Jesus had no water. It was probably not a supernatural fast, and he had water with him.
A person can survive without water for only about 3 days. In the case of Moses, the fast was a supernatural one.28 Moses was there with the LORD forty days and forty nights without eating bread or drinking water. And he wrote on the tablets the words of the covenant—the Ten Commandments.
Luke 4:
How could Jesus survive without food for 40 days even though he was fully human?2 where for forty days He was tempted by the devil. He ate nothing during those days, and when they had ended, He was hungry.
