John Wesley’s NotesPsalms 148

Heavens of heavens - Ye highest heavens, the place of God's throne. Waters - Ye clouds which are above a part of the heavens.

Established - He hath made them constant and incorruptible, not changeable, as the things of the lower world. A decree - Concerning their continuance.

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.

Fire - Lightnings and other fireworks of the air. Vapour - Or, fumes: hot exhalations. Fulfilling his word - Executing his commands, either for the comfort or punishment of the inhabitants of the earth.

Above - Above all the glories which are in earth and in heaven.

The horn - In scripture commonly denotes strength, victory, glory, and felicity.
