Commentary on Proverbs 1:7

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Proverbs 1:7-9: Solomon, having undertaken to teach a young man knowledge and discretion, here lays down two general rules to be observed in order thereunto, and those are, to fear God and honour his parents, which two fundamental laws of morality Pythagoras begins his golden verses with, but the former of them in a wretchedly corrupted state.
• John Gill (Reformed Baptist), Exposition of the Old and New Testaments on Proverbs 1:7: The fear of the Lord is the beginning of knowledge,.... Here properly the book begins, and this is the first of the proverbs, and an excellent one; it is such an one as is not to be found in all the writings of the Heathens.
• Jamieson-Fausset-Brown (Reformed), Commentary Critical and Explanatory on the Whole Bible on Proverbs 1:7: The fear of the Lord--the principle of true piety (compare Pro 2:5; Pro 14:26-27; Job 28:28; Psa 34:11; Psa 111:10; Act 9:31). beginning--first part, foundation. fools--the stupid and indifferent to God's character and government; hence the wicked.
• Keil & Delitzsch (Lutheran), Biblical Commentary on the Old Testament on Proverbs 1:1-7: The Book of Proverbs bears the external title ספר משׁלי, which it derives from the words with which it commences. It is one of the three books which are distinguished from the other twenty-one by a peculiar system of accentuation, the best exposition of which that has yet been given is that by S. Baer, as set forth in my larger Psalmen-commentar.
