a Bible passage
He will not grow faint or be crushed
until he has established justice in the earth;
and the coastlands wait for his teaching.
4. fail—faint; man in religion may become as the almost expiring flax-wick (Isa 42:3), but not so He in His purposes of grace.
discouraged—literally, "broken," that is, checked in zeal by discouragements (compare Isa 49:4, 5). Rosenmuller not so well translates, "He shall not be too slow on the one hand, nor run too hastily on the other."
judgment—His true religion, the canon of His judgments and righteous reign.
isles … wait, &c.—The distant lands beyond sea shall put their trust in His gospel way of salvation. Mt 12:21 virtually gives the sense, with the inspired addition of another aspect of the same thing, "In his name shall the Gentiles trust" (as "wait for" here means, Isa 30:18). "His law" is not something distinct from Himself, but is indeed Himself, the manifestation of God's character ("name") in Christ, who is the embodiment of the law (Isa 42:21; Jer 23:6; Ro 10:4). "Isles" here, and in Isa 42:12, may refer to the fact that the populations of which the Church was primarily formed were Gentiles of the countries bordering on the Mediterranean.
