Albert Barnes Commentary 1 Samuel 2:1

"And Hannah prayed, and said: My heart exulteth in Jehovah; My horn is exalted in Jehovah; My mouth is enlarged over mine enemies; Because I rejoice in thy salvation." — 1 Samuel 2:1 (ASV)

Hannah's song is a prophetic psalm; it is both poetry and prophecy. It takes its place alongside the songs of Miriam, Deborah, and the Virgin Mary, as well as those of Moses, David, Hezekiah, and other psalmists and prophets whose inspired odes are preserved in the Bible.

The special feature these songs share is that, while they spring from and initially relate to specific incidents in the lives of their authors, they branch out into magnificent descriptions of the Kingdom and glory of Christ and the triumphs of the Church. These original incidents were providentially designed to be types of those greater realities.

Understanding this principle is essential for interpreting Hannah's song. This connection is confirmed by comparing the marginal references throughout the text.
