Old Testament

The Book of Exodus: Chapter 17:8-14-16

 Now Amalek came and fought with Israel in Rephidim. And Moses said to Joshua, "Choose us some men and go out, fight with Amalek. Tomorrow I will stand on the top of the hill with the rod of God in my hand." So Joshua did as Moses said to him, and fought with Amalek. And Moses, Aaron, and Hur went up to the top of the hill. And so it was, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. But Moses' hands became heavy; so they took a stone and put it under him, and he sat on it. And Aaron and Hur supported his hands, one on one side, and the other on the other side; and his hands were steady until the going down of the sun. So Joshua defeated Amalek and his people with the edge of the sword.

Then the Lord said to Moses, "Write this for a memorial in the book and recount it in the hearing of Joshua, that I will utterly blot out the remembrance of Amalek from under heaven." And Moses built an altar and called its name, The-Lord-Is-My-Banner; for he said, "Because the Lord has sworn: the Lord will have war with Amalek from generation to generation."

New Testament

The Epistle of Paul the Apostle to the Romans: Chapter 10:14-21

How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written:

"How beautiful are the feet of those who preach the gospel of peace,
Who bring glad tidings of good things!"

But they have not all obeyed the gospel. For Isaiah says, "Lord, who has believed our report?"

So then faith comes by hearing, and hearing by the word of God. But I say, have they not heard? Yes indeed:

"Their sound has gone out to all the earth,
And their words to the ends of the world."
But I say, did Israel not know? First Moses says:

"I will provoke you to jealousy by those who are not a nation,
I will move you to anger by a foolish nation."

But Isaiah is very bold and says:

"I was found by those who did not seek Me;
I was made manifest to those who did not ask for Me."

But to Israel he says:

"All day long I have stretched out My hands
To a disobedient and contrary people."
