I have been reading a great Proverbs commentary for the last few years that I think will be a blessing to others. The author is the pastor of The Church of Greenville at Standing Springs(South Carolina), Jonathan Crosby. Jonathan is a stellar bible researcher with a high sensitivity to the accuracy and heart for the Word of God. He has written a commentary for close to 90% of the 900 verses in proverbs. Since they are so densely written then a commentary will assist as you build a scope of the Bible. There is an email sign up on his website if you would like to receive a new commentary every day.
