They answered and said unto him, {f} Thou wast altogether born in sins, and dost thou teach us? And they cast him out.

(f) You are wicked even from your cradle, and as we used to say, there is nothing in you but sin.

People's New Testament

9:34 They cast him out. If they could not answer his arguments they could excommunicate him. This they did. Observe that this miracle was officially investigated by the enemies of Christ, and they were compelled to admit it. The judicial investigation showed that he was born blind, that he was cured, and that Jesus gave him sight.

Wesley's Notes

9:34 Born in sin - And therefore, they supposed, born blind. They cast him out - Of the synagogue; excommunicated him.

King James Translators' Notes

cast...: or, excommunicated him

Matthew Henry's Concise Commentary

9:24-34 As Christ's mercies are most valued by those who have felt the want of them, that have been blind, and now see; so the most powerful and lasting affections to Christ, arise from actual knowledge of him. In the work of grace in the soul, though we cannot tell when, and how, and by what steps the blessed change was wrought, yet we may take the comfort, if we can say, through grace, Whereas I was blind, now I see. I did live a worldly, sensual life, but, thanks be to God, it is now otherwise with me, Eph 5:8. The unbelief of those who enjoy the means of knowledge and conviction, is indeed marvellous. All who have felt the power and grace of the Lord Jesus, wonder at the wilfulness of others who reject him. He argues strongly against them, not only that Jesus was not a sinner, but that he was of God. We may each of us know by this, whether we are of God or not. What do we? What do we for God? What do we for our souls? What do we more than others?
