Gregory the Dialogist : 31. For perfect men, because they are softened by no praise from the rigor of justice, are the same before as after the testimony of their praise, and they confirm by repeating afterward the same things they had said before. But we must ask what this signifies, that which is said: 'Today'. For if the life of the reprobate is night, what does it mean that Saul's kingdom is torn away in the day? But if the life of a reprobate pastor is night, when his kingdom is torn away, it makes day. For day does not come unless night departs. He says, therefore, 'Today', because the darkness of the disobedient one is declared to be condemned. Whence also, when Judas went out, the Lord says: 'Now is the Son of Man glorified' (John 13:31); because He saw the night of that man's life depart, and the pure light of justice remain in the other disciples. It is also said 'Today', because with the proud one removed, the kingdom was being handed over to the humble king. Whence it is also added: (Verse 28) 'And He has given it to your neighbor who is better than you.' When therefore "today" is said, nothing bright is seen in the rejected king, but the glory of his successor is proclaimed, who from the height of the kingdom was to shine with the splendor of great virtue. And asserting the immutability of the divine sentence, he adds, saying: (Verse 29) 'Moreover, the Triumphant One of Israel will not spare, and will not be moved by repentance.' — Commentary on 1 Kings, Book 6, Chapter 2
