(Proverbs 30:29 KJV) There be three things which go well, yea, four are comely in going:
Agur needs to make up his mind. Is it three or four? Notice from verse one that this chapter is not claimed by Solomon. Notice that first it says three, then four. If you read through Proverbs you will see this confusion appears several times. It is not confusion, it is a literary device. Like hyperbole, metaphor and personification, this is a way of getting your attention. Keep in mind that the Bible is not written as a manual to show you how to set up your new cell phone. It is a living book for living people in dynamic lives.
There are certain words that come up in regard to the Bible: Literal interpretation, inerrancy, contradictions. They point out that you need to read the Bible with your mind turned on and your reason engaged.
So? Ask questions. Assume there are answers. Don’t assume that you will understand all of them all of the time.
