John Wesley on Zechariah 14:21

Every pot - The utensils of private houses shall be all dedicated to God's service. That sacrifice - So the prophet expresses all religious affections, practice, and worship, which shall be as pleasing to God, as were the sacrifices of his people offered up with divine warrant and approbation. Seethe therein - That part of the sacrifice which pertaineth to the priests, and to the offerer to feast on. The Canaanite - Any of the accursed nation, or one who makes merchandise of religion. But all shall know that the Lord hath the greatest pleasure in upright, and sincere love and holiness.
