Jeremiah 1:11

Now our rod is the Word of God, Jesus Christ, as Jeremiah saw him as an almond rod. So everyone that spares his son a word of rebuke hates his son. Therefore teach your sons the word of the Lord. Punish them with lashes. Subdue them by your word of religion from their youth.

It is written in the book of the prophet, "Take a branch from a nut tree." So we must consider why the Lord said this to the prophet, for it is not written without a purpose, since we also read in the Pentateuch that the nut tree of Aaron, the priest, blossomed after it had been laid away for a long while.

(Verse 11, 12.) And the word of the Lord came to me, saying: What do you see, Jeremiah? And I said, I see a watching rod. And the Lord said to me: You have seen well, for I will watch over my word to perform it. For the watching rod, the Septuagint translated it as a nut-stick. Therefore, we must work so that the Latin reader understands the Hebrew etymology briefly. Seced is called a nut: but watching or watch or to watch is called Soced. And in the later [books], the leopard is placed in this position as a vigilant guardian. From this, therefore, because it is called a nut, due to the similarity of the word to the understanding of 'watchful', it alluded to the name: which indeed is also written in Daniel according to Theodotion, so that the dividing and cutting of the trees (namely oak and mastic) is appointed to adulterous priests. Likewise, in the beginning of Genesis, from the man who is called Is (), the woman is called Issa (), as some kind of mannish woman, because she is taken from man. For the nutcracker staff, the vigilant rod, the Eagle and Symmachus; but they transferred the almond to Theodotius. The rod, however, keeps watch, considering all the sins of the people, in order to strike and rebuke the transgressors. Therefore the Apostle writes to the sinners: What do you want? Shall I come to you with a rod, or in love and the spirit of gentleness? (1 Corinthians 4:21). This is the rod, or staff, that David speaks of: Your rod and your staff, they comfort me (Psalm 23:4). Beautifully he placed, they were consoled. For in this way the Lord corrects, so that he may amend. And just as a nut, or an almond, has a very bitter shell, and is surrounded by a very hard shell, so that when the bitter and hard parts are removed, the sweetest fruit is found: in the same way, all correction and the labor of self-restraint seem bitter for the present: but they produce the sweetest fruits. Hence that old saying: The roots of letters are bitter, the fruits are sweet. A certain rod and nut are understood to symbolize the Lord, of whom Isaiah says: 'A rod shall come forth from the root of Jesse' (Isaiah 11:1). Therefore, even the rod of Aaron, which was thought to be dead, is said to have blossomed at the resurrection of the Lord.
