Matthew 20:27

πρῶτος may be a synonym for μέγας = μέγιστος (De W.) and δοῦλος for διάκονος; or in both cases increased emphasis may be intended, πρῶτος pointing to a higher place of dignity, δοῦλος to a lower depth of servitude. Burton (M. and T. in N.T., § 68) finds in the two ἔσται in Matthew 20:26-27 probable instances of the third person future used imperatively.
