Haggai 2:15-16

The people needed to give careful consideration to something again (cf. Haggai 1:5; Haggai 1:7). They needed to remember that before they began to obey the Lord by rebuilding the temple (Haggai 1:12) they had been disobedient to the Mosaic Covenant (cf. Haggai 1:5-11). The Lord’s punishment for their covenant unfaithfulness had been greatly reduced harvests. Their grains had decreased by 50 percent and their grapes by 60 percent.
