We see types and shadows of our Lord Jesus Christ in almost every chapter of the bible. In Exodus 17 we see the children of Israel engaging in their first battle from their exodus out of Egypt. It was the Amalekites , the first of the nations, who came to fight with Israel in Rephidim (EX.17:8).
The Amalekites descended from the family of Esau (Gen.36:12). Esau also known as Edom (Gen.36:1,8) or Idumea (Isa.34:6). They were known as a very aggressive and warring nation who expanded a large area of land. They were eventually wiped out but scripture speaks of a latter day Edom or Idumea that represents ALL NATIONS that are against Israel (Isa.34:1-6).
The word “Edom” comes from the word “adam” or “man” and he represents the flesh.
So here in Exodus 17 , we see the children of Israel battling the Amalekites which represent the flesh or sin.
And we see Moses only prevailed when he had both his arms up (Ex.17:11). The record says:
“But Moses hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Hur stayed up his hands, the ONE ON THE ONE SIDE, and the OTHER ON THE OTHER SIDE ; and his hands were steady UNTIL THE GOING DOWN OF THE SUN.”
But Why did Moses have to raise his arms?
What might this picture remind us of?
Jesus Christ conquering sin on the cross.
The battle in Exodus 17 was a “type” or “shadow” of what would be accomplished. Not just on a physical battlefield but representing MORE than that: A Spiritual battle. It’s a battle that we all must fight , but as Moses could not do this by himself, the Lord Jesus Christ did do it all by himself. And we can ONLY be Victorious, in this man who would conquered sin for the salvation of the world.
Exodus 17:13 says “Joshua (or Yashua/another type of Christ”) discomfited Amalek and his people with the edge of the sword”. Jesus overcame the world by his sword, the Word of God (John 16:33). And he will do again when he puts down the “man of sin” and subdues the nations (2 Thess.2:8).
14 And Yahweh said unto Moses, Write this for a MEMORIAL in a book, and rehearse it in the ears of Joshua: for I will utterly put out the remembrance of Amalek from under heaven.
15 And Moses built an altar, and called the name of it Jehovahnissi (Yahweh is my Banner):
The battle against the Amalekites in Exodus 17 is a portrait of how Yahweh would manifest Himself in His son, on the cross.
