Psalms 148:7

“Praise the Lord from the earth, etc.] Let his praise resound from all creatures on earth, and reach him in the highest heavens; this phrase comprehends all terrestrial beings afterwards particularly mentioned; all in the terraqueous globe, all that arise from it, are upon it, or within it; ye dragons, and all deeps; either land dragons, or rather sea dragons, the water or sea being the proper place of them, (<194419>Psalm 44:19 74:13,14); these, as cruel, as poisonous, and pernicious as they are, are made to honour and praise the Lord, (<234320>Isaiah 43:20); and such as are mystically signified by, them, as Satan, tyrannical and persecuting princes, and antichristian ones, as Pharaoh king…”

“The call on the earth, as opposed to heaven, includes seas or depths, whose inhabitants the dragon, as one of the largest (on leviathan, see on Psa 104:26), is selected to represent. The most destructive and ungovernable agents of inanimate nature are introduced.”

“Praise the Lord from the earth - From among those who dwell on the earth. In respect to terrestrial objects, let these also unite in the praise of God. Ye dragons - On the meaning of this word, see Psalms 91:13, note; Isaiah 13:22, note. The word may mean a great fish, a whale, a sea monster, or a serpent.

Not merely the “dragons” or sea monsters, but all that inhabit the oceans. return to 'Top of Page'”

“Dragons - Either serpents, which hide in the deep caverns of the earth; or whales, and other sea - monsters, which dwell in the depths of the sea. Psalms 148:8”

“from the earth: Psa 148:1 ye dragons: Psa 74:13, Psa 74:14, Psa 104:25, Psa 104:26; Gen 1:21; Job 41:1-34; Isa 27:1, Isa 43:20, Isa 51:9, Isa 51:10 Psalms 148:8”

“The call to the praise of Jahve is now turned, in the second group of verses, to the earth and everything belonging to it in the widest extent. Here too מן־הארץ, like מן־השּׁמים, Psa 148:1, is intended of the place whence the praise is to resound, and not according to Psa 10:18 of earthly beings. The call is addressed in the first instance to the sea-monsters or dragons ( Psa 74:13), i.e., as Pindar (Nem. iii. 23f.) expresses it, θῆρας ἐν πελάγεΐ ὑπερο'χους, and to the surging mass of waters (תּהמות) above and within the earth. Then to four phenomena of nature, coming down from heaven and ascending heavenwards, which are so arranged in Psa 148:8, after the model of the chiasmus…”
