Exodus Chapter 17 Verse 4And Moses cried unto the LORD, saying, What shall I do unto this people? they be almost ready to stone me.

So the people rested on the seventh day.

And the house of Israel called the name thereof Manna: and it [was] like coriander seed, white; and the taste of it [was] like wafers [made] with honey.

And Moses said, This [is] the thing which the LORD commandeth, Fill an omer of it to be kept for your generations; that they may see the bread wherewith I have fed you in the wilderness, when I brought you forth from the land of Egypt.

And Moses said unto Aaron, Take a pot, and put an omer full of manna therein, and lay it up before the LORD, to be kept for your generations.

As the LORD commanded Moses, so Aaron laid it up before the Testimony, to be kept.

And the children of Israel did eat manna forty years, until they came to a land inhabited; they did eat manna, until they came unto the borders of the land of Canaan.

Now an omer [is] the tenth [part] of an ephah.

And all the congregation of the children of Israel journeyed from the wilderness of Sin, after their journeys, according to the commandment of the LORD, and pitched in Rephidim: and [there was] no water for the people to drink.

Wherefore the people did chide with Moses, and said, Give us water that we may drink. And Moses said unto them, Why chide ye with me? wherefore do ye tempt the LORD?

And the people thirsted there for water; and the people murmured against Moses, and said, Wherefore [is] this [that] thou hast brought us up out of Egypt, to kill us and our children and our cattle with thirst?

And the LORD said unto Moses, Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go.

Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink. And Moses did so in the sight of the elders of Israel.

And he called the name of the place Massah, and Meribah, because of the chiding of the children of Israel, and because they tempted the LORD, saying, Is the LORD among us, or not?

Then came Amalek, and fought with Israel in Rephidim.

And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with the rod of God in mine hand.

So Joshua did as Moses had said to him, and fought with Amalek: and Moses, Aaron, and Hur went up to the top of the hill.

And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed.

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.

And Joshua discomfited Amalek and his people with the edge of the sword.

And the LORD 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.
