The Song of Miriam is her response to the message God had given her. Miriam’s song can be divided into two main sections. In verses 46-50, she talks about what God did for her. In verses 51-56 she talks about what God will do for Israel. The song of Miriam shows the extent of her spirituality and her knowledge of Scripture. This is because many things stated here are very similar to Hannah’s Song in the book of I Samuel, chapter 2.

She makes two main points in her song. First, God is her Messiah. The kind of people that need a Messiah are sinners. By her own words she contradicts the teaching of the Immaculate Conception. The "Catholic Encyclopedia" states that the Immaculate Conception means that Miriam was born free of a sin nature. But, Miriam admits she is a sinner like the rest of us and needs a Messiah. There is probably an even more important reason for Matthew to include Miriam’s Song in his writings. By including Miriam’s Song, he ties Yeshua’s birth back directly to the birth of Samuel. Samuel was one of the greatest Old Testament prophets. In the Hebrew mind set, this shows Yeshua to be a prophet of God also. This is sort of what we call “guilt by association,” except there is no guilt in this association. Yeshua is destined to be the Greatest Prophet of all, God’s Anointed Messiah.
The second point of her song is that the One coming will fulfill the promises of the Abrahamic Covenant. Later in this commentary we will see how Yeshua’s death on the cross finally ratified the Abrahamic Covenant.
