Here is Christina Rossetti’s meditation on Good Friday. The reference to a stone and a rock being struck goes back to Exodus 17; see below.
Am I a stone, and not a sheep,
That I can stand, O Christ, beneath Thy cross,
To number drop by drop Thy blood’s slow loss,
And yet not weep?
Not so those women loved
Who with exceeding grief lamented Thee;
Not so fallen Peter weeping bitterly;
Not so the thief was moved;
Not so the Sun and Moon
Which hid their faces in a starless sky,
A horror of great darkness at broad noon –
I, only I.
Yet give not o’er,
But seek Thy sheep, true Shepherd of the flock;
Greater than Moses, turn and look once more
And smite a rock.
So the people were thirsty there for want of water, and murmured against Moses, saying: Why didst thou make us go forth out of Egypt, to kill us and our children, and our beasts with thirst? And Moses cried to the Lord, saying: What shall I do to this people? Yet a little more and they will stone me.
And the Lord said to Moses: Go before the people, and take with thee of the ancients of Israel: and take in thy hand the rod wherewith thou didst strike the river, and go. Behold I will stand there before thee, upon the rock Horeb: and thou shalt strike the rock, and water shall come out of it that the people may drink.
Moses did so before the ancients of Israel: And he called the name of that place Temptation, because the chiding of the children of Israel, and for that they tempted the Lord, saying: Is the Lord amongst us or not?
Exodus 17: 3-7
