My son, do not forget my teaching,
but keep my commands in your heart,
for they will prolong your life many years
and bring you prosperity.
Seems to me that Solomon is not only admonishing his son, but us as well, that the wisdom contained in the Proverbs is useful for prolonging life and bringing about prosperity.
Trust in the LORD with all your heart
and lean not on your own understanding;
in all your ways acknowledge him,
and he will make your paths straight.
Two of my favorite verses in the entire Bible, and the very first two I memorized. Such a great comfort and affirmation. When we trust in God with all that we are, He takes care of the rest and makes our paths straight. It’s only when we fail to do this that we end up in trouble.
Do not be wise in your own eyes;
fear the LORD and shun evil.
An admonition to not be haughty or proud. It seems that fearing God and shunning evil go hand-in-hand.
