Will pass away,
But my words
Will not pass away.”
ὁ οὐρανὸς καὶ ἡ γῆ παρελεύσεται, οἱ δὲ λόγοι μου οὐ μὴ παρέλθωσιν.
This is exactly the same, word for word, in Mark, chapter 13:31, and in Luke, chapter 21:33. Jesus said that heaven and earth would pass away (ὁ οὐρανὸς καὶ ἡ γῆ παρελεύσεται), but his words would not pass away (οἱ δὲ λόγοι μου οὐ μὴ παρέλθωσιν). This was a simple statement about the enduring quality of the words of Jesus.
