12 If someone carries a piece of sacred meat in his pocket, meat that is set apart for sacrifice on the altar, and the pocket touches a loaf of bread, a dish of stew, a bottle of wine or oil, or any other food, will these foods be made holy by such contact?" The priests said, "No."
Matthew Henry's Commentary on Haggai 2:12
Commentary on Haggai 2:10-19
(Read Haggai 2:10-19)
Many spoiled this good work, by going about it with unholy hearts and hands, and were likely to gain no advantage by it. The sum of these two rules of the law is, that sin is more easily learned from others than holiness. The impurity of their hearts and lives shall make the work of their hands, and all their offerings, unclean before God. The case is the same with us. When employed in any good work, we should watch over ourselves, lest we render it unclean by our corruptions. When we begin to make conscience of duty to God, we may expect his blessing; and whoso is wise will understand the loving-kindness of the Lord. God will curse the blessings of the wicked, and make bitter the prosperity of the careless; but he will sweeten the cup of affliction to those who diligently serve him.
