Exodus 3:2

The angel of the Lord.

It is properly. term of office, and not of nature, and is used to denote not only human and spiritual messengers, but also any of the impersonal agents, such as winds, fires, pestilences, remarkable dispensations, etc., which serve as. medium to make known the divine will, or to illustrate the divine operation in nature or providence. In fact, one of the most frequent uses of the term is as. personification of divine judgments.--Bush. What Moses saw was the flame of fire in the bush; what he recognized within was an intimation of the presence of God, who maketh "a flame of fire his angel" (Psalms 104:4). The words which Moses heard were those of God himself, as all ancient and most modern divines have held, manifested in the person of the Son who is the Word.-- Canon Cook.

A bush.

The seneh, "thorn-bush," or "bramble," is. species of acacia, common in the Sinai peninsula, rising in tangled thickets, and having long, stout and sharp thorns. It is here called the bramble--definitely--as the well-known desert bramble, or as the bramble of this divine appearance. Sinai was probably named from this seneh (senna) shrub, which abounds upon its sides and valleys. The shittah, or shittim tree, used so much in the construction of the tabernacle and its furniture, belongs to the same family.-- F. H. Newhall. The accompanying cut will give some idea of the acacia, or shittim wood.

The bush was not consumed.

The fire was supernatural, and did not affect the wood or vegetable life of the acacia tree. It was this strange fact that arrested the attention of Moses.
