Numbers 18:32

And ye shall bear no sin by reason of it, of enjoying their income with their own families, when ye have heaved from it the best of it, if only this provision were observed; neither shall ye pollute the holy things of the children of Israel by disregarding these ordinances, or by bringing the gifts of the Sanctuary into an unclean place, lest ye die. If so much depended upon the precepts of the types and the shadows of things to come, how much more does it behoove us Christians to observe the will of the Lord in all respects!
