Exodus 17:6

Now Moses was pasturing the flock of Jethro his father-in-law, the priest of Midian; and he led the flock to the west side of the wilderness and came to Horeb, the mountain of God.

“As for you, raise up your staff and stretch out your hand over the sea and split it, and the sons of Israel shall go through the midst of the sea on dry land.

“Take the rod; and you and your brother Aaron assemble the congregation and speak to the rock before their eyes, that it may yield its water. You shall thus bring forth water for them out of the rock and let the congregation and their beasts drink.”

It is eleven days’ journey from Horeb by the way of Mount Seir to Kadesh-barnea.

“He led you through the great and fearsome wilderness, with its fiery serpents and scorpions and thirsty ground where there was no water; He brought water for you out of the rock of flint.

“You gave bread from heaven for them for their hunger, You brought forth water from a rock for them for their thirst, And You said to them to enter in order to possess The land which You swore to give them.

You split open spring and river; You dried up ever-flowing rivers.

He was splitting the rocks in the wilderness And so gave them abundant drink like the ocean depths.

And in their heart they put God to the test By asking for food according to their desire.

“You called in distress and I rescued you; I answered you in the hiding place of thunder; I tested you at the waters of Meribah. Selah.

Do not harden your hearts, as at Meribah, As in the day of Massah in the wilderness,

He opened the rock and water flowed out; It ran in the dry places like a river.

Who turned the rock into a pool of water, The flint into a spring of water.

“Behold, I will do something new; Now it will spring forth; Will you not know it? I will even make a roadway in the wilderness, Rivers in the wasteland.

And they did not thirst when He led them through the waste places. He made the water flow out of the rock for them; He split the rock, and the water gushed forth.

and all drank the same spiritual drink, for they were drinking from a spiritual rock which followed them, and the rock was Christ.
