Haggai 2:12-13
If one bear holy flesh in the skirt of his garment, and with his skirt do touch bread, or pottage, or wine, or oil, or any meat, shall it be holy? And the priests answered and said, No. Then said Haggai, If one that is unclean by a dead body touch any of these, shall it be unclean? And the priests answered and said, It shall be unclean.
Numbers 19:22
And whatsoever the unclean person toucheth shall be unclean; and the soul that toucheth it shall be unclean until even.
Haggai's priestly ruling-consultation invokes the Numbers 19 transmission-of-uncleanness statute as the theological analogy for the covenant community's condition. The statutory principle establishes an asymmetry: holiness is not communicated outward through contact (Haggai's first question, answered No), but defilement is (Haggai's second question, answered Yes). Haggai applies this to the community: their incomplete temple-building work cannot sanctify their offerings, but their unclean covenant priorities have defiled everything they produce — the statutory asymmetry of defilement-transmission explains why the community remains under covenant curse despite renewed effort.
Haggai 2:17
I smote you with blasting and with mildew and with hail in all the labours of your hands; yet ye turned not to me, saith the LORD.
Deuteronomy 28:22
The LORD shall smite thee with a consumption, and with a fever, and with an inflammation, and with an extreme burning, and with the sword, and with blasting, and with mildew; and they shall pursue thee until thou perish.
Haggai identifies the blasting, mildew, and hail that the community experienced as the Deuteronomy 28 covenant curse categories: 'blasting and with mildew' appears verbatim in both texts. The LORD's review of the disciplinary measures invokes the Deuteronomic curse catalog as the statutory instrument of correction that the community ignored. The 'yet ye turned not to me' is the indictment that the statutory warning mechanism failed to produce the covenant return it was designed to generate.
Haggai 2:19
Is the seed yet in the barn? yea, as yet the vine, and the fig tree, and the pomegranate, and the olive tree, hath not brought forth: from this day will I bless you.
Deuteronomy 28:8
The LORD shall command the blessing upon thee in thy storehouses, and in all that thou settest thine hand unto; and he shall bless thee in the land which the LORD thy God giveth thee.
Haggai's 'from this day will I bless you' is the activation of the Deuteronomy 28 storehouse-blessing statute from the covenant blessing side. The Deuteronomic blessing commanded the blessing upon storehouses — the reversal of the empty-barn curse. Having cataloged the drought and curse, Haggai now announces the covenant's blessing side: with the foundation of the temple laid, the Deuteronomy 28 storehouse-blessing is now activated, reversing the curse cycle that had produced the bag-with-holes futility.
