V.1-4 The early chapters of Proverbs show us that the fear of the Lord is the only sure way to be preserved from evil. For the believer, behavior is of the greatest importance. Not to get our blessings, but to enjoy them. Remember, the Lord Jesus had not yet come to earth when Proverbs was written.
V.5-8 When we trust in the Lord, we obey Him. And when we obey Him, we have confidence in Him. One is the fruit of the other. So here. How foolish to rely on our own thoughts.
V.7 Eve, in the garden, listened to this from Satan. And he has been deceiving people ever since.
V.9-10 These promises of prosperity were for Israel. But we can transfer these to spiritual riches.
