John 7:13 - Albert Barnes' Notes on the Bible

Spake openly of him - The word translated “openly,” here, is commonly rendered “boldly.” This refers doubtless, to those who really believed on him. His enemies were not silent; but his friends had not confidence to speak of him openly or boldly that is, to speak what they really thought. Many supposed that he was the Messiah, yet even this they did not dare to profess. All that they could say in his favor was that he was a good man. There are always many such friends of Jesus in the world who are desirous of saying something good about him, but who, from fear or shame, refuse to make a full acknowledgment of him. Many will praise his morals, his precepts, and his holy life, while they are ashamed to speak of his divinity or his atonement, and still more to acknowledge that they are dependent on him for salvation.
