Every plant before it was in the earth That is, when there was neither any plant, nor so much as any seed from which any could spring: and when, as is here observed, the two great means of the growth of vegetables were both wanting, rain from heaven and the labour of man. So that they were evidently produced by the word of God's power alone. The English reader will observe in these two verses, the word LORD occurring for the first time. And he must remember that, whenever it occurs in our translation in capital letters, it stands for Jehovah. This is that name of God which implies self-existence, independence, and eternity, and signifies one that has being in and of himself, and is the source of being to all that exists. It is well explained by himself, Revelation 1:8, I am Alpha and Omega, the beginning and the ending, which is and was, and is to come; the Almighty!
