Matthew 24:40

Or otherwise; The body is laid as sick on the bed of carnal passions, the soul grinds in the mill of this world, and the bodily senses labour in the field of the world.

Or, the two in the field, are the two people of believers and unbelievers, whom the day of the Lord shall overtake, as it were in the labours of this life. And they shall be separated, one being taken and the other left; this shows the separation that shall be between believers and unbelievers; when God's wrath is kindled, the saints shall be gathered into His garner, and the unbelievers shall be left as fuel for the fire from heaven. The same is the account to be given of that, Two shall be grinding at the mill. The mill is the work of the Law, but as some of the Jews believed through the Apostles, so some shall believe through Elias, and be justified through faith; and one part shall be taken through this same faith of good works, the other part shall be left unfruitful in the work of the Law, grinding in vain, and never to produce the bread of heavenly food.

Then again He sets another sign, by all which things He makes it evident, that He is not ignorant of the day. And what is the sign? "Then shall two be in the field; one shall be taken, and one left. Two women shall be grinding at the mill, one shall be taken, and one left. Watch therefore, for ye know not what hour your Lord doth come." And all these things are both proofs that He knew, and calculated to turn them from their inquiry. So for this cause He spake also of the days of Noah, for this cause He said too, "Two shall be on the bed," signifying this, that He should come upon them thus unexpectedly, when they were thus without thought, and "two women grinding at the mill," which also of itself is not the employment of them that are taking thought. And together with this, He declares that as well servants as masters should be both taken and left, both those who are at ease, and those in toil, as well from the one rank as from the other; even as in the Old Testament He saith, "From him that sitteth upon the throne to the captive woman that is at the mill." For since He had said, that hardly are the rich saved, He shows that not even these are altogether lost, neither are the poor saved all of them, but both out of these and out of those are men saved, and lost. And to me He seems to declare, that at night will be the advent. For this Luke too saith. Seest thou how accurately He knows all things?

Or, Two men in one field shall be found performing the same labour, sowing corn together, but not reaping the same fruit of their labour.

Or, these words denote three orders in the Church. The two men in the field (prædicatores.) denote the order of preachers, to whom is committed the field of the Church; by the two grinding at the mill, (conjugati.) the order of the married priests, who while with a divided heart they are called first to one side, then to the other, do, as it were, ever turn round a mill; by the two in one bed, (continentes.) the order of the continent, whose repose is signified by the bed. But in all these orders are good and bad, righteous and unrighteous, so that some shall be taken, and some left.
