Hannah prayed, and said: My heart exults in Yahweh; My horn is exalted in Yahweh; My mouth is enlarged over my enemies; Because I rejoice in your salvation.
(5) The reference to the Lord's "king" in  1 Samuel 2:10 is said to assume a time AFTER the monarchy was established.  Such a conclusion is a gross error.  Hannah was familiar with the Pentateuch, and Moses had specifically prophesied that Israel, in time, would have a king  (Deuteronomy 13:14ff and  Deuteronomy 28:36ff), and Hannah's words here are a prophesy that God would give power and strength to such a king.  The real trouble that unbelieving critics have with this song is the prophetic element in it, but their wicked unbelief is of no significance whatever.
