Matthew 12:5

“Or have ye not read in the law, etc.] (<042809>Numbers 28:9) by which law the priests were obliged, every sabbath day, to offer up two lambs for a burnt offering; to which were annexed many servile works, as killing the sacrifice, flaying it, cutting it in pieces, and laying it on the altar, cutting of wood, and putting that in order, and kindling the fire: from all which, it might be observed, how that on the sabbath days, the priests in the temple profane the sabbath, and are blameless. There were many things, which, according to the Jewish canons, the priests might do on the sabbath day; particularly they might slay the sacrifice: it was a rule with them, tbç ta hjwjç htjd, “that slaying…”

“Or have ye not read in the law, how that on the sabbath days the priests in the temple profane the sabbath--by doing "servile work." and are blameless?--The double offerings required on the sabbath day (Num 28:9) could not be presented, and the new-baked showbread (Lev 24:5; Ch1 9:32) could not be prepared and presented every sabbath morning, without a good deal of servile work on the part of the priests; not to speak of circumcision, which, when the child's eighth day happened to fall on a sabbath, had to be performed by the priests on that day. (See on Joh 7:22-23).”

“How he entered into the house of God - That is, the “tabernacle,” the temple not being then built. Have ye not read in the law? - In the law, or in the books of Moses. Profane the Sabbath - He referred them to the conduct of the priests also. On the Sabbath days they were engaged, as well as on other days, in killing beasts for sacrifice, Numbers 28:9-10. Two lambs were killed on the Sabbath, in addition to the daily sacrifice. The priests must be engaged in killing them, and making fires to burn them in sacrifice, whereas to kindle a fire was expressly forbidden the Jews on the Sabbath, Exodus 35:3. They did that which, for other persons to do, would have been “profaning” the Sabbath. Yet…”

“The priests in the temple profane the Sabbath - That is, do their ordinary work on this, as on a common day, cleansing all things, and preparing the sacrifices. A greater than the temple - If therefore the Sabbath must give way to the temple, much more must it give way to me. Matthew 12:7”

“12:5-6 Priests worked on the Sabbath (Lev 24:8-9; Num 28:9-10), and this was not offensive to Pharisees. If the priests’ work for the Temple on the Sabbath is allowed, then certainly Jesus can do the same because he is greater than the Temple (see Matt 4:23; 9:35; 11:2-6, 20-30).”

“on: Num 28:9, Num 28:10; Joh 7:22, Joh 7:23 profane: Neh 13:17; Eze 24:21 Matthew 12:6”
