And Miriam sang to them: “Sing to the LORD, for he has triumphed gloriously; the horse and his rider he has thrown into the sea.”
Those who held their peace while deliverance was working must not hold it when the work is done. Singing psalms is the language of holy joy as prayer is of holy desire. Strike while the mercy is fresh; when the heart is most affected, praise returns quickest to God, before time and our own deceitfulness dull the impression.

Commenting on Exodus 15:1-21
Moses commanded the people forward from the Red Sea, where they had been refreshing themselves, gathering the spoils of Egypt, gold, silver, precious stones from the horses' harness, and singing God's praises. When he gave the word to march, they set out into the wilderness of Shur, the same desert called Etham, a particular district lying six hours' journey from where they crossed.
