Exodus 29:3

And thou shalt put them into one basket
The unleavened bread, cakes and wafers; this basket may be an emblem of the Gospel and the ministration of it, in which Christ the bread of life is carried, and ministered to his people:

and bring them in the basket, with the bullock and the two rams;
not that the bullock and the rams were to be brought in the basket along with the bread, cakes, and wafers; but at the same time that they were brought to the door of the tabernacle of the congregation, these were to be brought, led, or drove to the altar, in order to be slain and sacrificed.
