Deuteronomy 32:2

Deu. 32:2. God here speaks to the people quite in a different manner from what He did at Mount Sinai, when He spake to them out of the midst of the fire, with a great and terrible voice that was not suited to their tender frame, and that exceedingly terrified them, and was ready to destroy them. God's word then was like thunder and lightning and devouring fire, overbearing and consuming so frail and tender a creature as man, who is like the grass and flower of the field. God's voice is now gentle, delivered in a pleasant song; and instead of being like lightning to destroy and consume, is like the gentle showers and refreshing dew to the tender grass, instructing, reproving, warning, revealing not only His will, but His great mercy, in a manner adapted to man's tender frame. There is much of the glorious gospel in this song, and even the warnings and threatenings that are in it are delivered in an evangelical manner, much in the same way that they were delivered by the gentle voice of the glorious Messiah. All the songs of Scripture are the voice of the gospel. The glorious things of the gospel are their foundation and subject-matter, and therefore in them God's word drops as the rain, etc.
