Alternate translation: "also teach to those who are naive how to be wise" (See: [[rc://en/ta/man/jit/figs-abstractnouns]] and [[rc://en/ta/man/jit/figs-activepassive]])
The abstract nouns "knowledge" and "discretion" can be stated as verbs. Alternate translation: "and to teach to the youth what he needs to know and how to discern the right thing to do" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
