Melachim Bais 14:6

6 But the banim of the makkim (assassins, murderers) he slaughtered not; according unto that which is written in the Sefer Torat Moshe, wherein Hashem commanded, saying, The avot shall not be put to death for the banim, nor the banim be put to death for the avot; but every ish shall be put to death for his own chet (sin) [Dt. 24:16].

Which is an instance of his clemency and goodness, and of his strict regard to justice, and to the law of God; though he might fear, these, being spared, would one time or other revenge their fathers' deaths;

according to that which is written in the book of the law of Moses,
see ( Deuteronomy 24:16 ) ,

wherein the Lord commanded, saying, the fathers shall not be put to
death for the children, nor the children
to which command Amaziah was obedient.
