1 Samuel 1 - 3
This is the story of God’s dealings with Israel in the last days of the judges, and the transition of the nation from being a Theocracy (led by God) into a Monarchy (led by a king). Samuel is dedicated to the service of God from his birth, and he will not only be the last great judge in Israel, but he will also be a great prophet of God.
Eli is the high priest serving at God’s tabernacle in Shiloh, however God declares judgement against him and his sons, prophesying that the Lord will bring an end to his line as high priest, and set up a faithful high priest in his place.
Then I will raise up for Myself a faithful priest who shall do according to what is in My heart and in My mind. I will build him a sure house, and he shall walk before My anointed forever.
- 1 Samuel 2:35 NKJV
This is prophetic of Jesus, Who will ultimately become both King and High Priest in Israel, however there is also a more immediate fulfillment in the days of Solomon, when the line of Eli’s priesthood is cut off, and Zadok is appointed as high priest.
