By the word of the Lord; either,
1. By the hypostatical Word, Christ, who is oft called God's Word, even by the Chaldee paraphrast; as also 1 Thessalonians 1:1-3, where he is said to be that Word by whom all things were made. So that which is here spoken more darkly and doubtedly, according to that state of the church, is more clearly declared in the New Testament. Or,
2. By his will or command, as this very phrase is here used, Psalms 33:4, and as it seems to be explained, Psalms 33:9. And so it hath a great emphasis in it, that God made this admirable structure of the heavens, and all its glorious stars, not with great pains and time, and help of many artists and instruments, as men do far meaner works, but with one single word; which is much to the glory of the Creator. All the host of them; the angels; or the stars: See Poole on "Genesis 2:1". By the breath of his mouth; either,
1. By the Holy Ghost, so called Job 33:4. And so here are all the persons of the Trinity, Jehovah the Father, and the Word, and the Spirit; to each of which this work of creation is elsewhere ascribed, as was noted on Genesis 1:26. Or,
2. By his word, as it was expressed in the last clause, which is so called Isaiah 11:4 2 Thessalonians 2:8.
