'Fading' in the Bible

Now if the ministry of death, chiseled in letters on stones, came with glory, so that the Israelites were not able to look directly at Moses’ face because of the glory from his face—a fading glory—

For if what was fading away was glorious, what endures will be even more glorious.

We are not like Moses, who used to put a veil over his face so that the Israelites could not stare at the end of what was fading away,

On the other hand, I am writing to you a new commandment that is truly in him and in you. For the darkness is fading away, and the true light is already shining.

And the world and its desires are fading away, but the person who does God's will remains forever.
