Mark 4:23

If any man hath ears to hear, let him hear. 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.

Take heed what ye hear ... has the obvious meaning of enjoining selectivity in the things men choose to hear; but Dummelow advocated another reading as quite possible, "Understand (weigh well the meaning of) what ye hear."[25] Both ideas are valid Scriptural injunctions.

With what measure ye mete, etc. ... Euthymius paraphrased this thus: "In that measure in which you measure your attention to my teaching, in the same measure will spiritual understanding be measured unto you."[26]

Inherently: This one-sentence parable is true in any context. Thus the Lord applied it to the kind of judgments men give of others, resulting always in their being judged in the same fashion (Matthew 7:2). Again, the Saviour extended it in an application to the grace of giving (Luke 6:38).
