Isaiah 28:24 KJV

22Now therefore be ye not mockers, lest your bands be made strong: for I have heard from the Lord GOD of hosts a consumption, even determined upon the whole earth.

23Give ye ear, and hear my voice; hearken, and hear my speech.

24Doth the plowman plow all day to sow? doth he open and break the clods of his ground?

25When he hath made plain the face thereof, doth he not cast abroad the fitches, and scatter the cummin, and cast in the principal wheat and the appointed barley and the rie in their place?

26For his God doth instruct him to discretion, and doth teach him.
