Pseudo-Chrysostom — as excerpted in the Catena Aurea on Matthew 20:1-16

“Or; He says the first shall be last, and the last first, not that the last are to be exalted before the first, but that they should be put on an equality, so that the difference of time should make no difference in their station. That He says, For many are called, but few chosen, is not to be taken of the elder saints, but of the Gentiles; for of the Gentiles who were called being many, but few were chosen.”
