Psalms 148 - Dummelow's Commentary on the Bible

From the heavens] i.e. angels and the heavenly bodies.

This is the 'Gloria in Excelsis' of the Psalter, wherein all created things, animate and inanimate, are called upon to praise Jehovah.

Waters that be above the heavens] So God divided the waters: see Genesis 1:6; Genesis 1:7.

Which shall not pass] RM'which none shall transgress.'

Vapours] smoke or steam: cp. Psalms 119:83.

Excellent] RV 'exalted.'

RM 'a horn for his people, a praise for all his saints,' i.e. the giving victory to God's people ('exalting the horn') is a subject of praise.
