'Bush' in the Bible

And when forty years were expired, there appeared to him in the wilderness of mount Sina an angel of the Lord in a flame of fire in a bush.

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 Moses whom they refused, saying, Who made thee a ruler and a judge? the same did God send to be a ruler and a deliverer by the hand of the angel which appeared to him in the bush.
