John Trapp on Proverbs 30:18

Verſ. 18. There be three things which are too wonderful] The wiſeſt man that is, cannot give a reaſon of all things: as of the ebbing and flowing of the ſea, of the colours in the rain-bow, of the ſtrength of the nether chappe, and of the heat in the ſtomack, which conſumeth all other things, and yet not the parts about it. Agur here confeſſeth himſelf gravelled in four things at leaſt, and benighted.
