Every sabbath he shall set it in order. — That is, Aaron is to carry out these instructions in the first instance, as we are told in Leviticus 24:3, and after him, or together with him, the priests are sacredly to attend to this duty every sabbath throughout the year. Of the manner in which the shewbread, or the “bread of His Presence,” was renewed every Sabbath during the second Temple, we have a minute account. “Four priests entered the holy place, two of them carried in their hands the two piles of the cakes, and two carried in their hands the two incense cups, four priests having gone in before them, two to take off the two old piles, and two to take off the two incense cups. Those who brought in the new stood at the north side with their faces to the south, and those who took away the old stood at the south side with their faces to the north. As soon as the one party lifted up the old, the others put down the new, so that their hands were exactly over against each other, because it is written, before my Presence continually” (Exodus 25:30). The authorities during the second Temple took the expression “continually” to denote that the cakes were not to be absent for one moment. Hence the simultaneous action of the two sets of priests, one lifting up the old, and the other at once putting down the new shewbread.
Being taken from the children of Israel. — Like the daily sacrifices, the offerings for the congregation, the salt for the sacrifices, the wood for the altar, the incense, the omer (see Leviticus 23:10-11), the two wave-loaves (Leviticus 23:17), the scapegoat (Leviticus 16:5, &c.), the red heifer (Numbers 19:1-22), &c., the shewbread, or the “bread of His Presence,” according to the canon that obtained during the second Temple, were purchased with the people’s half-shekels, which every Israelite had to contribute annually toward the maintenance of the service in the sanctuary. (See Exodus 30:11-16.)
