Isaiah 30:18 - Joseph Benson’s Commentary on the Old and New Testaments

And therefore Because of your great misery: for the misery of God's people is frequently mentioned in Scripture as a motive to God's mercy: or, notwithstanding, as לכן may be rendered; will the Lord wait Patiently expect your repentance, and stop the course of his proceedings against you, that you may have an opportunity of making your peace with him, and of preventing your utter ruin. He will be exalted He will lift up himself, and exert his power gloriously in your behalf; that he may have mercy upon you That he may show his mercy in your deliverance. For the Lord is a God of judgment That is, he is wise and just in all the dispensations of his providence, acting toward his people with equity and moderation. Blessed are all they that wait for him In the way of their duty, with faith and patience; that will not take any indirect course to extricate themselves out of their straits, but patiently expect God to appear for them in his own way and time: which is a much surer way to safety and happiness than having recourse to mere human aids, and placing confidence in the arm of flesh.
