He that hath ears to hear, let him hear. A solemn exhortation, often spoken by our Lord at the close of an utterance. See Matthew 13:9, 43; Mark 4:23; Luke 14:35. It means—You are all formed by nature to learn God's commands; answer, therefore, to your powers, and obey him.
See Psalms 40:6 (cf. Hebrews 10:5).
