Psalms 148 - Wesley's Explanatory Notes

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.
