Job 38:7

“When the morning stars sang together, etc.] Either all the stars in a literal sense; for though, strictly speaking, there is but one morning star, yet all may be called so, because early created in the morning of the world; and are all stars of light, shine till the morning; and it is observed by some, that the nearer the morning the brighter they shine: and these in their way sing the praises of God, and set forth the glory of his perfections, and occasion songs of praise in men; (see <19E803>Psalm 148:3 19:1). Or figuratively, either angels, as most interpret them, comparable to stars for their glory, purity, and light, for their constancy, permanency, and numbers: or good men,…”

“So at the founding of Zerubbabel's temple (Ezr 3:10-13). So hereafter at the completion of the Church, the temple of the Holy Ghost (Zac 4:7); as at its foundation (Luk 2:13-14). morning stars--especially beautiful. The creation morn is appropriately associated with these, it being the commencement of this world's day. The stars are figuratively said to sing God's praises, as in Psa 19:1; Psa 148:3. They are symbols of the angels, bearing the same relation to our earth, as angels do to us. Therefore they answer to "sons of God," or angels, in the parallel. See on Job 25:5.”

“When the morning-stars - There can be little doubt that angelic beings are intended here, though some have thought that the stars literally are referred to, and that they seemed to unite in a chorus of praise when another world was added to their number. The Vulgate renders it, astra matutina, morning-stars; the Septuagint, ὅτε ἐγενήθηναι ἄστρα hote egenēthēnai astra - “ when the stars were made:” the Chaldee, “the stars of the zephyr,” or “morning” - צפר כוכבי. The comparison of a prince, a monarch, or an angel, with a star, is not uncommon; compare the notes at Isaiah 14:0. The expression “the morning-stars” is used on account of the beauty of the principal star which, at certain…”

“Stars - The angels, who may well be called morning - stars, because of their excellent lustre and glory. Sons of God - The angels called the sons of God, because they had their whole being from him, and because they were made partakers of his Divine and glorious image. Shouted - Rejoiced in and blessed God for his works, whereby he intimates, that they neither did advise or any way assist him, nor dislike or censure any of his works, as Job had presumed to do. Job 38:8”

“38:7 The morning stars are personified in parallel construction with the angels (1:6; 2:1).”

“the morning: Rev 2:28, Rev 22:16 the sons: Job 1:6, Job 2:1; Psa 104:4; Rev 5:11 shouted: Ezr 3:11, Ezr 3:12; Zac 4:7 Job 38:8”
