Haggai 2:12

The question was, if someone carries consecrated food in his garment and touches other food of any kind with the garment, will that food become holy? Holy meat was meat set apart for a particular sacrificial purpose (cf. Leviticus 6:25; Numbers 6:20). The answer was, no it would not become holy. The meat carried in the garment would make the garment holy, but the holiness would not be communicated beyond the garment to anything else (cf. Exodus 29:37; Leviticus 6:27; Ezekiel 44:19; Matthew 23:19). The people were apparently thinking that since they were working on the holy temple all that they contacted and did became holy. Another view is that the Lord sought to discourage His people from taking gifts from pagan rulers and using them to build the temple (cf. Ezra 6:8-10). [Note: See Merrill, pp. 45-46, 49.]
