After rebutting the untenable grounds of excuse, Haggai calls attention in vv. 5, 6 to the curse with which God has punished, and is still punishing, the neglect of His house. Hag 1:5. “And now, thus saith Jehovah of hosts, Set your heart upon your ways. Hag 1:6. Ye have sowed much, and brought in little: ye eat, and not for satisfaction; drink, and not to be filled with drink: ye clothe yourselves, and it does not serve for warming; and the labourer for wages works for wages into a purse pierced with holes.” שִׂימוּ לְבַבְכֶם, a favourite formula with Haggai (cf. v. 7 and Hag 2:15, Hag 2:18). To set the heart upon one's ways, i.e., to consider one's conduct, and lay it to heart. The ways are the conduct, with its results. J. H. Michaelis has given it correctly, “To your designs and actions, and their consequences.” In their ways, hitherto, they have reaped no blessing: they have sowed much, but brought only a little into their barns. הָבֵא, inf. abs., to bring in what has been reaped, or bring it home. What is here stated must not be restricted to the last two harvests which they had had under the reign of Darius, as Koehler supposes, but applies, according to Hag 2:15-17, to the harvests of many years, which had turned out very badly. The inf. abs., which is used in the place of the finite verb and determined by it, is continued in the clauses which follow, אָכוֹל, etc. The meaning of these clauses is, not that the small harvest was not sufficient to feed and clothe the people thoroughly, so that they had to “cut their coat according to their cloth,” as Maurer and Hitzig suppose, but that even in their use of the little that had been reaped, the blessing of God was wanting, as is not only evident from the words themselves, but placed beyond the possibility of doubt by Hag 1:9.
(Note: Calvin and Osiander see a double curse in Hag 1:6. The former says, “We know that God punishes men in both ways, both by withdrawing His blessing, so that the earth is parched, and the heaven gives no rain, and also, even when there is a good supply of the fruits of the earth, by preventing their satisfying, so that there is no real enjoyment of them. It often happens that men collect what would be quite a sufficient quantity for food, but for all that, are still always hungry. This kind of curse is seen the more plainly when God deprives the bread and wine of their true virtue, so that eating and drinking fail to support the strength.”)
What they ate and drank did not suffice to satisfy them; the clothes which they procured yielded no warmth; and the ages which the day-labourer earned vanished just as rapidly as if it had been placed in a bag full of holes (cf. Lev 26:26; Hos 4:10; Mic 6:14). לֹו after לְחֹם refers to the individual who clothes himself, and is to be explained from the phrase חַם לִי, “I am warm” (1Ki 1:1-2, etc.).
