(15) In returning and rest . . .--The words describe a process of conversion, but the nature of that conversion is determined by the context. In this case it was the turning from the trust in man, with all its restless excitement, to a trust in God, full of calmness and of peace.

Verse 15. - For thus saith the Lord God, the Holy One of Israel. As the irreligious party wished to hear no more of "the Holy One of Israel" (ver. 11), Isaiah takes care to keep him constantly before their minds (comp. Isaiah 31:1). In returning and rest shall ye be saved; rather, should ye be saved, or might ye be saved. The conditions are put forward, not as now capable of being realized, but as those which might have been realized at an earlier date. The "returning" spoken of is an abandonment of the course hitherto pursued, which was reckless provocation of Assyria and trust in Egypt. The "rest" is staying upon God - renunciation of trust on any arm of flesh, and simple reliance on the Divine aid, as sure to be sufficient when the need came. In quietness and confidence shall be your strength; rather, should be. The clause is a mere iteration in other words of the preceding one. Ye would not. They had practically rejected the policy of quiescence and patient waiting upon God, when they sent the embassy into Egypt.

30:8-18 The Jews were the only professing people God then had in the world, yet many among them were rebellious. They had the light, but they loved darkness rather. The prophets checked them in their sinful pursuits, so that they could not proceed without fear; this they took amiss. But faithful ministers will not be driven from seeking to awaken sinners. God is the Holy One of Israel, and so they shall find him. They did not like to hear of his holy commandments and his hatred of sin; they desired that they might no more be reminded of these things. But as they despised the word of God, their sins undermined their safety. Their state would be dashed in pieces like a potter's vessel. Let us return from our evil ways, and settle in the way of duty; that is the way to be saved. Would we be strengthened, it must be in quietness and in confidence, keeping peace in our own minds, and relying upon God. They think themselves wiser than God; but the project by which they thought to save themselves was their ruin. Only here and there one shall escape, as a warning to others. If men will not repent, turn to God, and seek happiness in his favour and service, their desires will but hasten their ruin. Those who make God alone their confidence, will have comfort. God ever waits to be gracious to all that come to him by faith in Christ, and happy are those who wait for him.For thus saith the Lord GOD, the Holy One of Israel,.... This is still repeated, though displeasing to the carnal Jews, who, notwithstanding their ill behaviour to the Lord, condescends to give them the best advice, as follows:

in returning and rest shall ye be saved; or "may be saved" (o); this is the right and the only way, namely, by "returning" from their evil ways, particularly their purpose of going to Egypt for help, and by returning to God by repentance and reformation, and to his worship and ordinances; and so the Targum,

"if ye return to my law;''

and by "resting" quietly at home, and reposing their trust in the Lord:

in quietness and in confidence shall be your strength; in a quiet submission to the will of God, and in quietly waiting upon him for the issue and event of things, abiding in their own houses, and not in a hurrying tumultuous manner, running here and there for help; and in a holy and humble confidence in the Lord, and in the power of his might, where they should find such strength and security, as Pharaoh king of Egypt could not give them:

and ye would not; would not be persuaded to keep at home, and from going down to Egypt; would not take the advice given, but pursue their own measures and methods of salvation. This is the literal sense of the words; and if they can be accommodated to spiritual and eternal salvation, it may be done in this way: repentance may be meant by "returning", and faith by "rest"; or by "returning and rest" may be designed returning to rest, that is, to Christ, who is the only rest to weary souls: "quietness" may intend peace of conscience, arising from the blood and righteousness of Christ; and "confidence" faith, and an assurance of it, which make men strong Christians; though their strength does not barely lie in these graces, but in the object of them: now faith and repentance are blessings of the covenant of grace, gifts of God, and graces of the Spirit, which go together in the doctrine of salvation, and have a concern in it; though they are not meritorious procuring causes, nor conditions of it; yet in this way God brings his people to salvation, and they enter into, and are descriptive of, the character of such that are saved; there is so close a connection between these and salvation, that none are saved without them; and it may be observed, that this way of saving men through faith and repentance, and by going to Christ alone for rest, and by placing confidence in, and deriving all peace and comfort from him, is disagreeable to unregenerate men; which is a proof of the wretched depravity, and corruption, and perverseness of the will of man.
