1 Kings 19:5
And as he lay and slept under a juniper tree, behold, then an angel touched him, and said unto him, Arise and eat. [Dake Bible]
As he lay down to sleep under the juniper tree, being exhausted by the flight from Jezebel, an angel touched him – not to take his life in answer to his prayer, but to feed him and prepare him for a long journey.
The angel did this twice. His fare was very simple, but mighty under God’s blessing – merely a cake baked on coals and a cruise of water.
No doubt food never tasted better to a worn runner. He ate the first cake and drank the water; they lay down again to sleep under the personal protection of the angel.
Being awakened by the angel a second time, Elijah was told the journey was too great for him without eating and drinking again of the angel’s cooking.
He went in the strength of such food for 40 days and 40 nights, and came to Horeb, the Mount of God. [v5-8].
