Jeremiah 23:28 The prophet that hath a dream, let him tell a dream; and he that hath my word, let him speak my word faithfully. What is the chaff to the wheat? saith the Lord.

What is chaff to wheat? As a prophet I only get to ask the question. This whole chapter of Jeremiah is a dressing down of the prophets who said more than they were told to say. So as a prophet, I do not get to tell you the meaning.

Luckily the office of a prophet no longer exists so as a student of the Word and a teacher of the Word, I can share in my discovery.

Chaff is a lite dry husk that encapsulates the wheat grains. It needs to be separated from the grain to render the wheat pure and ready for use. Where this occurs is important. Because the chaff is lite and dry, it is easily blown away by the wind whereas the wheat grain is heavier and will fall to the floor of the threshing stone. Where is the best place to perform this separation? On a high treeless mount.

2 Samuel 24:2  And Araunah said, Wherefore is my lord the king come to his servant? And David said, To buy the threshingfloor of thee, to build an altar unto the Lord, that the plague may be stayed from the people.

Araunah, also known as Ornan in 1 Chronicles 21:15, owned the perfect threshing floor, on Mount Moriah. Yes, the same mount where Abraham took Isaac to be sacrificed and God stayed the hand of Abraham in that sacrifice. Sound familiar?

2 Samuel 24:16 And when the angel stretched out his hand upon Jerusalem to destroy it, the Lord repented him of the evil, and said to the angel that destroyed the people, It is enough: stay now thine hand. And the angel of the Lord was by the threshingplace of Araunah the Jebusite.

So where the chaff is separated from the wheat is more important than the effort.
