Augustine of Hippo
Catena Aurea · Matthäusevangelium 27
And they that passed by reviled him, wagging their heads, And saying, Thou that destroyest the temple, and buildest it in three days, save thyself. If thou be the Son of God, come down from the cross. Likewise also the Chief Priests mocking him, with the Scribes and elders, said, He saved others; himself he cannot save. If he be the King of Israel, let him now come down from the cross, and we will believe him. He trusted in God; let him deliver him now, if he will have him: for he said, I am the Son of God. The thieves also, which were crucified with him, cast the same in his teeth.
(de Cons. Ev. iii. 16.) It may seem that Luke contradicts this, when he describes one of the robbers as reviling Him, and as therefore rebuked by the other. But we may suppose that Matthew, shortly alluding to the circumstance, has used the plural for the singular, as in the Epistle to the Hebrews we have, Hare stopped the months of lions, (Heb. 11:33.) when Daniel only is spoken of. And what more commonway of speaking than for one to say, See the country people insult me, when it is one only who has done so. If indeed Matthew had said that both the thieves had reviled the Lord, there would be some discrepancy; but when he says merely, The thieves, without adding ‘both,’ we must consider it as that common form of speech in which the singular is signified by the plural.
