'Bush' in the Bible

"After 40 years had passed, an angel appeared to him in the flames of a burning bush in the desert near Mount Sinai.

When Moses saw it, he was amazed at the sight, and when he approached the bush to look at it, the voice of the Lord said,

"This same Moses whom they rejected by saying, "Who made you ruler and judge?' was the man whom God sent to be both their ruler and deliverer with the help of the angel who had appeared to him in the bush.
