Matthew Henry on Exodus 17:8–end
We have here the story of the war with Amalek, which, we may suppose, was the first that was recorded in the book of the wars of the Lord, Num 21:14. Amalek was the first of the nations that Israel fought with, Num 24:20. Observe,
I. Amalek's attempt: They came out, and fought with Israel, Exo 17:8. The Amalekites were the posterity of Esau, who hated Jacob because of the birthright and blessing, and this was an effort of the hereditary enmity, a malice that ran in the blood, and perhaps was now exasperated by the working of the promise towards an accomplishment.

By his direction they fought, and in his name and strength they conquered; each one feeling himself, not his own, but the Lord's soldier.
John Gill on Exodus 17:15
And Moses built an altar,.... On Horeb, as Aben Ezra; on the top of the hill, as Ben Gersom, where sacrifices of thanksgiving were offered up for the victory obtained, or however a monument erected in memory of it:
