judge not, lest ye be judged

1. proverb If you judge or condemn someone else, you stand to be judged or condemned according to the same standard; do not judge unsympathetically or hypocritically. The phrase was said by Jesus in the Bible (Matthew 7:1). A: "Well, I just think homeless people should stop being so lazy and go get a job already." B: "Wow, I'll remember that if you ever lose your job and struggle to find a new one. Judge not, lest ye be judged."

2. proverb It is not your place to judge or condemn other people, because others are sure to find things for which to judge or condemn you. This more common interpretation of the phrase ignores the line in the Bible that follows: "For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again." (Matthew 7:2) A: "You know, you really should lay off the sweets." B: "Hey, judge not, lest ye be judged!"

lest we forget

Used to emphasize the need to remember (someone or something). Lest we forget all of the men and women who bravely gave their lives during the war, we can come visit them here, their final resting place. I know you're frustrated that Amelia's been acting out lately, but, lest we forget, she's only 16. I think her behavior is pretty normal, in the scheme of things. Lest we forget, the Owls have the worst record in the league—by far. So you can sugarcoat our loss to them however you want, but it's still embarrassing.

Judge not, lest ye be judged.

and Judge not, that ye be not judged.

Prov. If you condemn other people, then they will have the right to condemn you, so it is best not to condemn them. (Biblical.) Jill: I'm sure Gloria is the one who's been stealing from petty cash. She's so sloppy, nasty, and ill-mannered. Don't you think she'd be capable of theft? Jane: Judge not, lest ye be judged.
