The war with Amalek
Pattern
The first war Israel fights as a nation ends with an oath: the Lord will have war with Amalek from generation to generation. Deuteronomy commands the blotting out, Saul is rejected for leaving it unfinished, and an Agagite rises against the Jews in the days of Esther.
The first command in Scripture to write anything is the command to record this war. What God swears in Exodus is still in force in Persia centuries later, and the books in between measure their kings by what they did with it. Saul loses the kingdom over this order, and the reason is stated to him at the end from the grave's edge.
Amalek attacks at Rephidim
Then came Amalek, and fought with Israel in Rephidim.
Write it in a book
The first command in Scripture to write anything, and the oath: the LORD will have war with Amalek from generation to generation.
Remember, and blot out
The charge is renewed on the edge of the land: thou shalt blot out the remembrance of Amalek; thou shalt not forget it.
Saul spares Agag
Ordered to end the war, Saul and the people spare the king and the best of the spoil.
The stated ground of rejection
Because thou obeyedst not the voice of the LORD, nor executedst his fierce wrath upon Amalek.
Esther 3:1 you are here
Haman the Agagite
The enemy of the Jews in Persia carries Agag's name.
