Matthew 24:40

See that the word divides humans into two ranks — the saved and the destroyed. He says the saved are taken along, and the destroyed are left, that is, rejected. By “field” here understand the world, where “the one sowing to the Spirit harvests eternal life, and the one sowing to the flesh, corruption.” He likens teachers to the women grinding, who in a way thin out the scriptural thoughts and set the divine oracles before humans as easily accepted and easily understood. For the law also, commanding that a millstone or upper millstone not be taken in pledge so that someone who takes the tools of food may not hinder those fed through them, indicates teachers in a riddle.

The Lord divides humans into two ranks — the saved and the destroyed. He says the saved are taken along, and the impious are left, which is to be rejected. He likens teachers to the women grinding as thinning the scriptures and making them easily accepted and easily understood by humans. For the law also forbids taking a millstone or upper millstone in pledge, so that someone who takes the tools of food may not become an obstacle to those being fed. That is why the Savior also indicates teachers in a riddle.
