'In The Desert' in the Bible

He replied, "I am the voice of a man who is calling out in the desert, [urging people to] 'Make the road for the Lord straight,' as Isaiah the prophet said, [Isa. 40:3]."

Our forefathers ate the [supernatural] 'manna' in the desert, as it is written [Neh. 9:15], 'He gave them bread from heaven to eat.'"

Your forefathers ate the 'manna' in the desert and died.

Now it was almost time for the Jewish Festival of Tabernacles [Note: This was also called "Festival of Shelters," and was one of three principal, annual Jewish festivals and commemorated the occasion of the Israelites living in tents or shelters during their forty year wandering in the desert].
