"As a dog returneth to his vomit, so a fool returneth to his folly." -- Proverbs 26:11
Quite the analogy! The Book of Proverbs is all about being wise and not an idiot, because idiots will suffer if they don't strive to learn and understand the laws of God. Some other gems:
"The fear of the Lord is the beginning of knowledge: but fools despise wisdom and instruction." Proverbs 1:7
"For wisdom is better than rubies; and all the things that may be desired are not to be compared to it." -- Proverbs 8:11
"Pride goeth before destruction, and an haughty spirit before a fall." -- Proverbs 16:18
And I especially feel I have a lot to learn from this one: "He that is slow to anger is better than the mighty: and he that ruleth his spirit than he that taketh a city." -- Proverbs 16:32
This book was supposedly written by King Solomon and a few other, lesser known people. It's part of the wisdom literature (Job, Psalms, Proverbs, Ecclesiastes, Song of Songs) in the Bible, a collection of books that teach about how to discover the "tree of life" through a search for understanding. Took me three days to read Proverbs, at about 10 chapters a day. At this rate I should be finished reading the whole Bible by early October.
