Then said the LORD unto me,
You have well seen: for I will hasten my word to perform it.
Read Chapter 1
Ambrose of Milan
AD 397
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. - "Letter 62"
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. - "Didascalia 22.[4.11]"
