And therefore will the LORD wait, that he may be {q} gracious to you, and therefore will he be exalted, that he may have mercy upon you: for the LORD is a God of

(r) judgment: blessed are all they that wait for him.

(q) He commends the great mercies of God, who with patience waits to call sinners to repentance.

(r) Not only in punishing but in using moderation in the same, as in Jer 10:24,30:11.

Wesley's Notes

30:18 Wait - Patiently expect your repentance. Exalted - He will work gloriously. Judgment - Or mercy. That wait - In his way, with faith and patience.

Jamieson-Fausset-Brown Bible Commentary

18. therefore-on account of your wicked perverseness (Isa 30:1, 2, 9, 15, 16), Jehovah will delay to be gracious [Horsley]. Rather, wait or delay in punishing, to give you time for repentance (Isa 30:13, 14, 17) [Maurer]. Or, "Yet therefore" (namely, because of the distress spoken of in the previous verses; that distress will lead the Jews to repentance, and so Jehovah will pity them) [Gesenius].

be exalted-Men will have more elevated views of God's mercy; or else, "He will rise up to pity you" [G. V. Smith]. Or (taking the previous clause as Maurer, "Therefore Jehovah will delay" in punishing you, "in order that He may be gracious to you," if ye repent), He will be far removed from you (so in Ps 10:5, far above out sight); that is, He will not immediately descend to punish, "in order that He may have mercy," &c.

judgment-justice; faithfulness to His covenant.

wait-compare Isa 30:15, wait, namely, for His times of having mercy.

Matthew Henry's Concise Commentary

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.
