The title in the Hebrew Bible is “The Proverbs of Solomon“ (1:1), as also in the Greek Septuagint (LXX). Proverbs pulls together the most important 513 of the over 3,000 proverbs pondered by Solomon (1 Kin. 4:32; Eccl. 12:9), along with some proverbs of others whom Solomon likely influenced. The word “proverb” means “to be like,” thus Proverbs is a book of comparisons between common, concrete images and life’s most profound truths. Proverbs are simple, moral statements (or illustrations) that highlight and teach fundamental realities about life. Solomon sought God’s wisdom (2 Chr. 1:8–12) and offered “pithy sayings” designed to make men contemplate 1) the fear of God and 2) living by His wisdom (1:7; 9:10). The sum of this wisdom is personified in the Lord Jesus Christ (1 Cor. 1:30).

“TITLE. This Psalm may be regarded as THE PREFACE PSALM, having in it a notification of the contents of the entire Book. It is the psalmists’s desire to teach us the way to blessedness, and to warn us of the sure destruction of sinners. This, then, is the matter of the first Psalm, which may be looked upon, in some respects, as the text upon which the whole of the Psalms make up a divine sermon.
DIVISION. This Psalm consists of two parts: in the first (from verse 1 to the end of the 3rd) David sets out wherein the felicity and blessedness of a godly man consisteth, what his exercises are, and what blessings he shall receive from the Lord. In the second part (from verse 4 to the end) he contrasts the state and character of the ungodly, reveals the future, and describes, in telling language, his ultimate doom.”
