The Bible uses rain as a metaphor for a spectrum of good and evil. A #merism in a single word. At one extreme is drought. At the other is hail and fire. Righteousness and life are right in the middle. Moses prays that his speech will fall like light rain, the perfect good for Israel.
The Song of Moses begins and ends with praise for the God of Heaven. Much like the Lord's Prayer as taught by Yeshua.
