Do not rebuke mockers or they will hate you; rebuke the wise and they will love you.
Instruct the wise and they will be wiser still; teach the righteous and they will add to their learning. Proverbs 9:8-9
One person gives freely, yet gains even more; another withholds unduly, but comes to poverty. Proverbs 11:24
Gray hair is a crown of splendor; it is attained in the way of righteousness. Proverbs 16:31
Better a dry crust with peace and quiet than a house full of feasting, with strife. Proverbs 17:1
Do not wear yourself out to get rich; do not trust your own cleverness.
Cast but a glance at riches, and they are gone, for they will surely sprout wings and fly off to the sky like an eagle. Proverbs 23:4-5
If anyone loudly blesses their neighbor early in the morning, it will be taken as a curse. Proverbs 27:14
It's amazing to me that even hundreds of years later, these proverbs are still applicable. I guess we don't really change much as humans over the years. It reminds me of Ecclesiastes when it says "there is nothing new under the sun". I also love how witty some of these are. It would have been fun to be around Solomon and whoever else were coming up with these. I picture these older men sitting around a bar or a campfire trying to out do each other in who could come up with the best saying. But it probably wasn't as exciting as that.
