Charles Ellicott Commentary Mark 4:24

"And he said unto them, Take heed what ye hear: with what measure ye mete it shall be measured unto you; and more shall be given unto you." — Mark 4:24 (ASV)

With what measure ye mete.—See Note on Matthew 7:2. The proverb provides a good illustration of what has just been said regarding our Lord’s method of presenting the same truth under different aspects. In the Sermon on the Mount it appears as the law of retribution, which brings pardon to those who pardon, judgment without mercy to those who show no mercy.

Here the law works in another region. With the measure with which we measure our knowledge, God will, in His bounty, bestow more knowledge on us. The old maxim, Docendo disces (“You will learn by teaching”), becomes here more than the lesson of experience, and is one with the divine law of equity.
