Isaiah 5:21

Woe unto therm that are wise in their own eyes ,.... And yet betray such stupidity and sottishness, as to call things by their wrong names; and make such a perverse judgment of them, as before described. This is a true description of the Scribes and Pharisees in Christ's time; who said, "dost thou teach us? are we blind also?" John 9:34 .

and prudent in their own sight ; being wise above what was written; leaving the word of God, and following the traditions of the elders.
