Luke 6:39-42 New International Version (NIV)
39 He also told them this parable: “Can the blind lead the blind? Will they not both fall into a pit? 40 The student is not above the teacher, but everyone who is fully trained will be like their teacher.
41 “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? 42 How can you say to your brother, ‘Brother, let me take the speck out of your eye,’ when you yourself fail to see the plank in your own eye? You hypocrite, first take the plank out of your eye, and then you will see clearly to remove the speck from your brother’s eye.
