Zechariah 8:15

So have I turned and purposed in these days to do well unto Jerusalem - Dionysius: "God, to be better understood, speaketh with the feelings and after the manner of men, although, in the passionless and unchangeable God, there is no provocation to anger, nor turning, implying change in Himself." So He says by Jeremiah, "I know the thoughts that I think toward you, saith the Lord, thoughts of peace and not of evil" Jeremiah 29:11. And, with the same contrast as here, "As I have watched over them to pluck up and to break down and to throw down, and to destroy and to afflict, so will I watch over them, to build and to plant, saith the Lord" Jeremiah 31:28. His having done what He purposed before was an earnest the more, that He would do what He purposed now. His chastisements were the earnests of His mercies; for they too were an austere form of His love. Osorius: "When the Lord stretches out His hand to strike those who are contumacious in guilt, none can hold His hand that He exact not the due punishment. Therefore He says, that He repented not; so, when He receives to grace those who repent of their sins, no one can any way delay the course of His benevolence. "For the gifts and calling of God are without repentance" Romans 11:29.

And to the house of Judah - Ribera: He speaks to the two tribes, not to, or of the ten, because Christ was to come to the two tribes, and Zechariah was prophesying to them, and they were to be admonished to prepare themselves in good works, lest the coming of Christ should not profit them, on account of their depraved ways. But the ten tribes were far off in the cities of the Medes, nor was Christ to come to them; but they were to hear the Gospel through the Apostles, and so he prophesies of the conversion of all to the glory of Christ, yet he could not admonish all, but those only to whom he was sent.

8:15 So - So with like steadiness of mind I have purposed to do well to you.
