Charles Ellicott Commentary Haggai 1:12-15

"Then Zerubbabel the son of Shealtiel, and Joshua the son of Jehozadak, the high priest, with all the remnant of the people, obeyed the voice of Jehovah their God, and the words of Haggai the prophet, as Jehovah their God had sent him; and the people did fear before Jehovah. Then spake Haggai Jehovah`s messenger in Jehovah`s message unto the people, saying, I am with you, saith Jehovah. And Jehovah stirred up the spirit of Zerubbabel the son of Shealtiel, governor of Judah, and the spirit of Joshua the son of Jehozadak, the high priest, and the spirit of all the remnant of the people; and they came and did work on the house of Jehovah of hosts, their God, in the four and twentieth day of the month, in the sixth [month], in the second year of Darius the king." — Haggai 1:12-15 (ASV)

The Second Utterance. —The people turn a willing ear to Haggai’s exhortation, and the prophet is now charged to inform them of the return of God’s favour, in the gracious utterance, “I am with you, saith the Lord.”
