The angel of the Lord. — Heb., an angel of Jehovah. In Exodus 3:4 the angel is called both “Jehovah and “Elohim,” whence it is concluded, with reason, that it was the Second Person of the Trinity who appeared to Moses.
Out of the midst of a bush. — Literally, out of the midst of the acacia. As the seneh, or acacia, is very common in the Sinaitic region, we can scarcely suppose that a special tree, growing alone, is intended. Probably the article is one of reference, and the meaning is, “the bush of which you have all heard.” (Comp. John 3:24.)
