The religious leaders were watching Jesus to see if He would violate the “Traditions of the Elders” by healing on the Sabbath. Jesus calls them out by healing a man with a withered hand.
Generally speaking it is not smart to walk into an ambush on purpose. Unless of course, you have the fire power you need to take such a risk. The religious leaders were looking for solid evidence that Jesus was doing something wrong on the Sabbath. But their standards of right and wrong were based on a faulty premise. Instead of a correct interpretation the Word of God, the religious leaders went to their traditions. There’s an old saying, “Never bring a knife to a gun fight.” The religious leaders had no grounds for their accusations because their traditions carried no authority. Nowhere in the Law does it prohibit healing on the Sabbath (or doing any essential good deed for that matter) and Jesus knew it. The Word of God reigns supreme over all other writings or thought. To top it off, their poor judgment on the application of the Sabbath laws (Ex. 20: 8-11; 23:12-17; Deut. 5:12-15) prevented them from doing what God would naturally applaud. Their religious rules prevented them from loving people and that ticks God off! (Mk 3.5)
