Dallas has categorized the proverbs so that they are easily found under key words. While the categorization may not be perfect, it provides a good start for locating the proverb you want. I was also pleased to note that Dallas uses the New King James Version of the Bible. It's, in my view, a good translation for preserving the essence of the Bible as intended by the authors.
I think this is an excellent reference. It can be used by lay people and is also a handy reference for sermon preparation and for Bible study groups. I highly recommend this book as an addition to your library of Bible study tools.
I reviewed this book as part of the Thomas Nelson Booksneeze Program.
