The Pharisees and scribes criticized the disciples of Jesus for not keeping the tradition of the elders by failing to wash their hands before eating bread, to which Jesus gave this stinging rebuke,

He answered and said to them, “Well did Isaiah prophesy of you hypocrites, as it is written:

‘This people honors Me with their lips,
But their heart is far from Me.
And in vain they worship Me,
Teaching as doctrines the commandments of men.’

For laying aside the commandment of God, you hold the tradition of men—the washing of pitchers and cups, and many other such things you do” (Mark 7:6–8).

They did not realize that they had elevated the commandments of men over the commandments of God.

If they did not realize what they had done, is it possible that we also may have violated His will without realizing it?
