He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me. Howbeit in vain do they worship me, teaching for doctrines the commandments of men. For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
(Mar 7:6-8)

I find an interesting lesson in the small word “ye” of v.8.  The previous verses were quoting Isaiah and talking in general about “this people” (certain of the people of Israel).  However, in v.8, when Jesus amplified what the Scriptures, He did not stay with the more generic “they” or “some people” – He was very pointed that He was addressing the Pharisees and scribes that had come to Him, asking about the practice of His disciples.

Jesus could have easily avoided confrontation or controversy by keeping the point generic, but the fact that He said “ye” shows us that truth is more important then getting along with people.  We should never go out of our way to be unpleasant; we should always attempt to be kind to everyone — however, never at the expense of the truth.
