15:1ff Music played an important part in Israel’s worship and celebration. Singing was an expression of love and thanks, and it was a creative way to pass down oral traditions. Some say this song of Moses is the oldest recorded song in the world. It was a festive epic poem celebrating God’s victory, lifting the hearts and voices of the people outward and upward. After having been delivered from great danger, they sang with joy! Psalms and hymns can be great ways to express relief, praise, and thanks when you have been through trouble.
15:20 Miriam was called a prophetess not only because she received revelations from God (Micah 6:4) but also because of her musical skill. Prophecy and music were often closely related in the Bible (1 Samuel 10:5; 1 Chronicles 25:1). Miriam’s timbrel was an instrument shaped like a circle and ringed with brass pieces. It was similar to the tambourine.
15:23, 27 The water in the oasis of Marah is contrasted with the springs in the oasis of Elim. Marah stands for the unbelieving, grumbling attitude of the people who would not trust God. Elim stands for God’s bountiful provision. How easy it is to grumble and complain too quickly, only to be embarrassed by God’s help! We must be patient for God’s kindness and help. Don’t let your negative attitude erode your trust in God.
15:26 God promised that if the people obeyed him, they would not suffer from the diseases that plagued the Egyptians. Little did they know that many of the moral laws he later gave them were designed to keep them free from sickness. For example, following God’s law against prostitution would keep them free of venereal disease. God’s laws for us are often designed to keep us from harm. Men and women are complex beings. Our physical, emotional, and spiritual lives are intertwined. Modern medicine is now acknowledging what these laws assumed. If we want God to care for us, we need to submit to his directions for living.
