John 7:19

Did not Moses give you the law, and yet none of you doeth the law? Why seek ye to kill me?

Thus Jesus publicly exposed the plot to kill him on a trumped-up charge of sabbath-breaking, pointing out at the same time the paradox of such notorious violators of Moses' law, as were the Pharisees, plotting to kill Jesus for, of all things, breaking the sabbath. None of the Pharisees kept the sabbath strictly, enjoying a hundred petty little exemptions from the rigorous rules they imposed on others, deserving the comment Jesus made of them: "Yea, they bind heavy burdens and grievous to be borne, and lay them on men's shoulders; but they themselves will not move them with their finger" (Matthew 23:4).

Keep the sabbath day? Of course, they did not. They circumcised on the sabbath; and they had devised some kind of a bypass for practically all of the sabbath restrictions. For example, with reference to walking no more than seven-eighths of a mile, which was the allowable distance according to their rules for a sabbath's journey, they often walked long distances, pausing each seven-eighths of a mile to partake of a bite of food previously cached there in anticipation of the journey, and thus taking any length journey on the pretext that they had changed their residence at each pause! Here, Jesus openly charged them with not keeping Moses' law.

Why seek ye to kill me ...? Why such men would seek to kill the holy Son of God is a part of the mystery of iniquity.
