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
Justin Martyr
AD 165
Jacob, as I have remarked before, being himself a type of Christ, had married the two handmaids of his two free wives and had sons by them. He did this to indicate ahead of time that Christ would receive even all those who among Japheth’s race are descendants of Canaan equally with the free and would have their children be heirs with them. This is what we are. But you cannot comprehend this because you cannot drink of the living fountain of God but of broken cisterns that can hold no water, as the Scripture says.
