2:10-19 Many spoiled this good work, by going about it with unholy hearts and hands, and were likely to gain no advantage by it. The sum of these two rules of the law is, that sin is more easily learned from others than holiness. The impurity of their hearts and lives shall make the work of their hands, and all their offerings, unclean before God. The case is the same with us. When employed in any good work, we should watch over ourselves, lest we render it unclean by our corruptions. When we begin to make conscience of duty to God, we may expect his blessing; and whoso is wise will understand the loving-kindness of the Lord. God will curse the blessings of the wicked, and make bitter the prosperity of the careless; but he will sweeten the cup of affliction to those who diligently serve him.

18. Resumed from Hag 2:15 after Hag 2:16, 17, that the blessing in Hag 2:19 may stand in the more marked contrast with the curse in Hag 2:16, 17. Affliction will harden the heart, if not referred to God as its author [Moore].

even from the day that the foundation of … temple was laid—The first foundation beneath the earth had been long ago laid in the second year of Cyrus, 535 B.C. (Ezr 3:10, 11); the foundation now laid was the secondary one, which, above the earth, was laid on the previous work [Tirinus]. Or, translate, "From this day on which the temple is being begun," namely, on the foundations long ago laid [Grotius]. Maurer translates, "Consider … from the four and twentieth day … to (the time which has elapsed) from the day on which the foundation … was laid." The Hebrew supports English Version.
