Jamieson, Fausset and Brown on Haggai 1:12

12. remnant of the people--all those who have returned from the exile (Zec 8:6).

as ... God sent him--according to all that Jehovah had enjoined him to speak. But as it is not till Hag 1:14 after Haggai's second message (Hag 1:13) that the people actually obeyed, Maurer translates here, "hearkened to the voice of the Lord," and instead of "as," "because the Lord had sent him." However, English Version rightly represents their purpose of obedience as obedience in God's eyes already, though not carried into effect till Hag 1:14.
