Blessed is the man whom thou chastenest, O LORD, and teachest him out of thy law; Blessed is the man whom thou chastenest - תיסרנו teyasserennu, whom thou instructest; and teachest him out of thy law. Two points here are worthy of our most serious regard:
1. God gives knowledge to man: gives him understanding and reason.
2. He gives him a revelation of himself; he places before that reason and understanding his Divine law.
This is God's system of teaching; and the human intellect is his gift, which enables man to understand this teaching. We perhaps may add a third thing here; that as by sin the understanding is darkened, he gives the Holy Spirit to dispel this darkness from the intellect, in order that his word may be properly apprehended and understood. But he gives no new faculty; he removes the impediments from the old, and invigorates it by his Divine energy.
