For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed themselves out cisterns, broken cisterns, that can hold no water.
All Commentaries on Jeremiah 2:13 Go To Jeremiah 2
Tertullian of Carthage
AD 220
This “tree” is a mystery. In ancient times, Moses sweetened the bitter water with it. The people who were perishing of thirst in the desert drank and were revived because of it. We do this, too. We were drawn out from the calamities of the world in which we were lingering, perishing with thirst (that is, deprived of the divine Word). We drank “by the faith which is on him,” the baptismal water of the “tree” of the passion of Christ. We have revived the faith from which Israel has fallen away, as foretold through Jeremiah, who says, “Send, and continue to ask whether such things have been done, whether nations will change their gods (and these are not gods!). But my people have changed their glory for that which does not profit. Be appalled at this, O heavens!”—and when were they appalled? Undoubtedly when Christ suffered—“and be shocked,” he says, “utterly desolate.”
