 The phrase you’re referring to comes from the Bible, specifically from Gospel of Matthew 7:2 and similarly in Gospel of Luke 6:38.

In the Gospel of Matthew 7:2, Jesus Christ says:

“For with the judgment you pronounce you will be judged, and with the measure you use it will be measured to you.”

Meaning

This teaching means:

• The way you treat others will be the way you are treated.
• The standard you apply to others will be applied to you.
• It’s a warning against harsh judgment and hypocrisy.

In context, Jesus is teaching about mercy, humility, and self-examination before criticizing others.

If you’d like, I can also explain how this connects to forgiveness, karma-like principles, or how different Christian traditions interpret it.
