Exodus 15 records what may well be the oldest song ever sung. It is the song of deliverance:
Exodus 15
1 Then Moses and the Israelites sang this song to the LORD: “I will sing to the LORD. He has won a glorious victory. He has thrown horses and their riders into the sea.
2 The LORD is my strength and my song. He is my Savior. This is my God, and I will praise him, my father’s God, and I will honor him.
3 The LORD is a warrior! The LORD is his name.
4 He has thrown Pharaoh’s chariots and army into the sea. Pharaoh’s best officers were drowned in the Red Sea.
5 The deep water covered them. They sank to the bottom like a rock.
6 Your right hand, O LORD, wins glory because it is strong. Your right hand, O LORD, smashes your enemies.
7 With your unlimited majesty, you destroyed those who attacked you. You sent out your burning anger. It burned them up like straw.
The children of Israel sang this song after the Red Sea parted and Pharoah’s army drowned.
The problem: anyone can sing this song after the fact. God is looking for people who will sing the song of deliverance while still in the problem! Israel had not learned anything. Three days later they were murmuring again.
I will sing this song now before God brings the deliverance!
