“Do not condemn!
Then you will not be condemned.”
καὶ μὴ καταδικάζετε, καὶ οὐ μὴ καταδικασθῆτε.
This unique saying of Luke indicated that Jesus continued to expand on not judging others by telling them they were not to condemn others (καὶ μὴ καταδικάζετε). Then they themselves would not be condemned (καὶ οὐ μὴ καταδικασθῆτε). Luke emphasized this mercifulness to a greater degree. Have you ever condemned someone?
