John 9:8,9

The neighbours, therefore Those who lived in the beggar's neighbourhood, and those who had frequently passed by where he used to beg, being well acquainted with his form and visage, were astonished at the alteration which they observed in his countenance, by reason of the new faculty that was bestowed upon him. Wherefore they expressed their surprise by asking one another, if this was not the blind man to whom they used to give alms. Some said, This is he; others, He is like him “The circumstance of having received his sight would give him an air of spirit and cheerfulness, which would render him something unlike what he was before, and might occasion a little doubt to those who were not well acquainted with him.” Doddridge. But he said, I am he The very man that so lately sat and begged; I am he that was blind, and was an object of the charity of men, but now see, and am a monument of the mercy and grace of God. We do not find that the neighbours appealed to him in this matter; but he, hearing the debate, interposed, and put an end to it. It is a piece of justice we owe to our neighbours, to rectify their mistakes, and to set things before them, as far as we are able, in a true light. Applying it spiritually, it teaches us that those who are savingly enlightened by the grace of God, should be ready to own what they were before that blessed change was wrought. See 1 Timothy 1:13.
