Note 4 at Mr 11:16: Only Mark pointed out that Jesus would not suffer anyone to carry any vessel through the temple. No explanation was offered by Mark as to why Jesus would not allow this. It is probable that Jesus wanted His Father's house to be dedicated completely to prayer and the ministry of God. Also, as with the Sabbath, work symbolizes our own effort, and our own effort will always fall short of what God demands for salvation. Therefore, anything that resembles work was inappropriate in the house of God.
