Ezekiel 46:15

Thus shall they prepare
This shows that not a single person is meant in the preceding verses, but all the Lord's people; who are all priests unto God, and who are to offer up daily spiritual sacrifices unto him: the lamb, and the meat offering, and the oil every morning, for a
continual burnt offering;
which is repeated for the confirmation of it, and to excite a careful and constant attention to it.
