Jeremiah 12:8

"My inheritance became to me as a lion in a thicket." This inheritance of his upon the earth, which he had received as inheritance, turned savage against him, and the inheritance — the Jews — became wild against him "as a lion in a thicket." It is no wonder if then his inheritance became "as a lion in a thicket"; even now there are still lions in the thicket wishing to curse Jesus and blaspheming him and plotting against those who believe in him. "My inheritance," then, "became to me as a lion in a thicket.

And although the Apostle himself told the Hebrews that a testament is of no force, until the death of the testator happen, that is to say, a testament is of no strength while the testator liveth, but is established by his death, yet as in Jeremiah the Lord, speaking of the Jews, has said, Mine heritage is unto Me as a lion, he would not deny that they were heirs. But there are heirs without possessions, there are heirs also with them; and while the testator lives those whose names are written in the will are called heirs, though without possessions... As then young children, so the Jews also, are under a schoolmaster. The Law is our schoolmaster, the schoolmaster brings us to our Master; and our One Master is Christ: Neither be ye called masters, for one is your Master, even Christ.

As the prophet Jeremiah testifies when he speaks such things … "I have forsaken my house, I have given up my heritage into the hand of its enemies. My heritage has become to me as a lion in the forest. It has cried out against me, therefore have I hated it." Since the inheritance is his heavenly kingdom, it is evident that he does not say that he hates the inheritance itself, but the heirs, who have been ungrateful toward him and impious. "My heritage," he says, "has become to me as a lion," that is, I have become prey and something to devour to my heirs, who have slaughtered me as a sheep. "It cried out against me," that is, they have pronounced against me the sentence of death and the cross. For that which he said … that he would make a new testament to the house of Judah, shows that the old testament that was given by Moses was not perfect, but that that which was to be given by Christ would be complete. But it is plain that the house of Judah does not signify the Jews, whom he casts off, but us, who have been called by him out of the Gentiles and have by adoption, succeeded to their place, and are called children.

Now that the Jews were disinherited, because they rejected Christ, and that we, who are of the Gentiles, were adopted into their place is proved by the Scriptures. Jeremiah thus speaks, "I have forsaken my house. I have given my heritage into the hands of its enemies. My heritage has become to me as a lion in the forest. It has given forth its voice against me; therefore have I hated it."

It is further related that when Pilate wanted to release him, the whole multitude shouted in uproar: "Crucify him, crucify him." This was foretold by the prophet Jeremiah, speaking in the person of the Lord: "My inheritance," he says, "has become to me as lion in the wood. It has cried out against me. Therefore have I hated it." And therefore, he adds, "I have forsaken my house." In yet another passage Isaiah says: "Upon whom have you opened your mouth wide, and against whom have you let loose your tongues?"
