[255] However, out of the common charges, baked bread [was set on the table of shew-bread], without leaven, of twenty-four tenth deals of flour, for so much is spent upon this bread; two heaps of these were baked, they were baked the day before the sabbath, but were brought into the holy place on the morning of the sabbath, and set upon the holy table, six on a heap, one loaf still standing over against another; where two golden cups full of frankincense were also set upon them, and there they remained till another sabbath, and then other loaves were brought in their stead, while the loaves were given to the priests for their food, and the frankincense was burnt in that sacred fire wherein all their offerings were burnt also; and so other frankincense was set upon the loaves instead of what was there before. The [high priest also, of his own charges, offered a sacrifice, and that twice every day. It was made of flour mingled with oil, and gently baked by the fire; the quantity was one tenth deal of flour; he brought the half of it to the fire in the morning, and the other half at night. The account of these sacrifices I shall give more accurately hereafter; but I think I have premised what for the present may be sufficient concerning them.
