So Moses said to Joshua, "Choose some of our men and go out, fight against Amalek. Tomorrow I will stand on top of the hill with the staff of God in my hand."

Call on me in prayer and I will answer you. I will show you great and mysterious things which you still do not know about.'

Then

I beat them to death; they fall at my feet.

When evil men attack me to devour my flesh, when my adversaries and enemies attack me, they stumble and fall.

So when Jesus said to them, "I am he," they retreated and fell to the ground.

For

The Lord who commands armies is on our side! The God of Jacob is our protector! (Selah)

You will be broken, O nations; you will be shattered! Pay attention, all you distant lands of the earth! Get ready for battle, and you will be shattered! Get ready for battle, and you will be shattered!

What then shall we say about these things? If God is for us, who can be against us?

General references

Whenever Moses would raise his hands, then Israel prevailed, but whenever he would rest his hands, then Amalek prevailed.
