'Thresh' in the Bible

Ornan turned around and saw the angel. While his four sons with him ran away to hide, Ornan continued to thresh wheat.

"See, I'm making you into a new, sharp, and multi-tooth threshing sledge. You'll thresh and crush the mountains, and make the hills like chaff.

"Ephraim, the well-trained heifer, loves to thresh grain, so I will spare her neck. I will turn Ephraim into a pack animal. Judah will pull the plow, and Jacob will turn up the fallow ground.

Isn't he really speaking for our benefit? Yes, this was written for our benefit, because the one who plows should plow in hope, and the one who threshes should thresh in hope of sharing in the crop.
