“Thus saith the Lord, I am returned to Zion,.... The temple being now building, and almost finished, and the worship of God restored in it. The Targum renders it, "I will return to Zion"; and it may refer to the time of Christ's incarnation, when the Redeemer came to Zion, Isa 59:20 or to the time of the conversion of the Jews in the latter day, of both which it is true; see Rom 11:26, and will dwell in the midst of Jerusalem: or "cause my Shechinah to dwell there", as the Targum paraphrases it; which was fulfilled when the Word was made flesh, , "and dwelt" or "tabernacled" among the inhabitants of Judea and of Jerusalem, and taught his doctrines, and wrought his miracles, in the midst of them; and will be also when he shall dwell among them by his Spirit and grace in the latter day: and Jerusalem shall be called a city of truth; when Christ, who is "truth" itself, was in it, and the truths of the Gospel were preached there by him and his apostles, and they were received and professed by many, though despised by others; and especially in the latter day, when the Jews shall generally and cordially embrace Christ and his Gospel, and shall worship God in spirit and in truth, and not in that shadowy, formal, and hypocritical way they do now; see Isa 1:26 and especially this will be true of the New Jerusalem, into which nothing shall enter that makes a lie, Rev 21:27, the mountain of the Lord of hosts; which will be established upon the top of the mountains, and where the Lord will be seen and exalted in his glory, even the Lamb, with the hundred and forty four thousand with him, Isa 2:2, the holy mountain; where the holy word of God will be preached, the holy ordinances administered, and holiness of life and conversation will be strictly attended to; yea, Holiness will be upon the bells of the horses, Zac 14:20.”

“I was jealous - Some refer this to the Jews themselves. They were as the spouse of Jehovah: but they were unfaithful, and God punished them as an injured husband might be expected to punish an unfaithful wife. Others apply it to the enemies of the Jews. Though I gave them a commission to afflict you, yet they exceeded their commission: I will therefore deal with them in fury - in vindictive justice.”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
