2The tongue of the wise commends knowledge,
but athe mouths of fools pour out folly.

Proverbs 15:28

28The heart of the righteous bponders how to answer,
but cthe mouth of the wicked pours out evil things.

Matthew 15:14

14Let them alone; dthey are blind guides.
Some manuscripts add of the blind
And fif the blind lead the blind, both will fall into a pit.”

Matthew 23:16-26

16Woe to gyou, hblind guides, who say, iIf anyone swears by the temple, it is nothing, but if anyone swears by the gold of the temple, he is bound by his oath.’ 17You blind fools! For which is greater, the gold or jthe temple that has made the gold sacred? 18And you say, ‘If anyone swears by the altar, it is nothing, but if anyone swears by kthe gift that is on the altar, he is bound by his oath.’ 19You blind men! For which is greater, the gift or lthe altar that makes the gift sacred? 20So whoever swears by the altar swears by it and by everything on it. 21And whoever swears by the temple swears by it and by mhim who dwells in it. 22And whoever swears by nheaven swears by othe throne of God and by phim who sits upon it.

23 qWoe to you, scribes and Pharisees, hypocrites! For ryou tithe mint and dill and scumin, and have neglected the weightier matters of the law: tjustice and mercy and faithfulness. uThese you ought to have done, without neglecting the others. 24You blind guides, straining out a gnat and swallowing va camel!

25 wWoe to you, scribes and Pharisees, hypocrites! For xyou clean the outside of ythe cup and the plate, but inside they are full of zgreed and self-indulgence. 26You blind Pharisee! First clean the inside of aathe cup and the plate, that the outside also may be clean.

Luke 6:39-40

39He also told them a parable: abCan a blind man lead a blind man? Will they not both fall into a pit? 40 acA disciple is not above his teacher, but everyone when he is adfully trained will be like his teacher.
