4 He shall not fail nor be discouraged, discouraged: Heb. broken till he have set judgment in the earth: and the isles shall wait for his law.
English Standard Version
4 He will not grow faint or be discouragedOr bruised till he has established justice in the earth; and the coastlands wait for his law.
4 He won't tire out and quit. He won't be stopped until he's finished his work - to set things right on earth. Far-flung ocean islands wait expectantly for his teaching." The God Who Makes Us Alive with His Own Life
New King James Version
4 He will not fail nor be discouraged, Till He has established justice in the earth; And the coastlands shall wait for His law."
New Living Translation
4 He will not falter or lose heart until justice prevails throughout the earth. Even distant lands beyond the sea will wait for his instruction. "
This prophecy was fulfilled in Christ, Matthew 12:17. Let our souls rely on him, and rejoice in him; then, for his sake, the Father will be well-pleased with us. The Holy Spirit not only came, but rested upon him, and without measure. He patiently bore the contradiction of sinners. His kingdom is spiritual; he was not to appear with earthly honours. He is tender of those oppressed with doubts and fears, as a bruised reed; those who are as smoking flax, as the wick of a lamp newly lighted, which is ready to go out again. He will not despise them, nor lay upon them more work or more suffering than they can bear. By a long course of miracles and his resurrection, he fully showed the truth of his holy religion. By the power of his gospel and grace he fixes principles in the minds of men, which tend to make them wise and just. The most distant nations wait for his law, wait for his gospel, and shall welcome it. If we would make our calling and election sure, and have the Father delight over us for good, we must behold, hear, believe in, and obey Christ.
