Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD binds up the hurt of his people, and heals the stroke of their wound.

Why should the lunar reckoning be calculated from the noontide hours, seeing that the moon had not yet been placed in the heavens or gone forth over the earth? On the contrary, none of the feast days of the law began and ended at noon or in the afternoon, but all did so in the evening. Or else perchance it is because sinful Adam was reproached by the Lord “in the cool of the afternoon” and thrust out from the joys of Paradise. In remembrance of that heavenly life which we changed for the tribulation of this world, the change of the moon, which imitates our toil by its everlasting waxing and waning, ought specifically to be observed at the hour in which we began our exile. In this way every day we may be reminded by the hour of the moon’s changing of that verse, “a fool changes as the moon” while the wise man “shall live as long as the sun,” and that we may sigh more ardently for that life, supremely blessed in eternal peace, when “the light of the moon shall be as the light of the sun,...
Moreover, when the day of judgment has been completed and the glory of the future life has become evident with the new heaven and the new earth, then will come to pass what the same prophet announced elsewhere: “The light of the moon will be as the light of the sun, and the light of the sun will be increased sevenfold, like the light of seven days.” - "Exposition of the Gospel of Mark 4.13.24"
But when there will be a new heaven and a new earth after the judgment—which is not one heaven and earth replacing another but these very same ones which will shine forth, having been renewed by fire and glorified by the power of the resurrection—then, as Isaiah predicts, “The light of the moon will be as the light of the sun, and the light of the sun will be sevenfold, as the light of seven days.” - "The Reckoning of Time 6.70"
Sevenfold. Exceedingly great, equal to the light of 49 days. (Calmet)
The fame of Ezechias spread widely. His kingdom was a figure of that of Christ, when this was more perfectly realized, the preaching of the gospel having dispelled the darkness of error. (Calmet)
He alludes to the day of judgment. (St. Jerome) (Menochius)
Does not Scripture say universally of all the things that were created by God, “Behold, everything that God made was very good”? … The things that belong to the present, then, are not declared good in a merely minimal sense but are emphatically “very good.” For, in fact, they are useful for us while we are living in this world, whether to sustain life or as medicine for the body or on account of some benefit unknown to us. Or else they are very good in that they let us “see the invisible things of God, his eternal power and his divinity, from the creation of the world, through things that have been made graspable”—that is, from the great and well-ordered construction and arrangement of the world—and let us contemplate them from the existence of everything that is in it. Yet all of these will be unable to maintain their title to goodness if they are compared with the future age, where no mutability in good things and no corruption of true blessedness is to be feared. The blessedness of ...
