John Calvin Commentary Matthew 1:24

"And Joseph arose from his sleep, and did as the angel of the Lord commanded him, and took unto him his wife;" — Matthew 1:24 (ASV)

Joseph, being raised from sleep. The ready performance, which is here described, serves no less to attest the certainty of Joseph’s faith than to commend his obedience. For, if every scruple had not been removed, and his conscience fully pacified, he would never have proceeded so cheerfully, upon a sudden change of opinion, to take unto him his wife, whose society he lately thought would pollute him.¹¹⁴ The dream must have carried some mark of Divinity, which did not allow his mind to hesitate. Next followed the effect of faith. Having learned the will of God, he instantly prepared himself to obey.

¹¹⁴ “Laquelle un peu auparavant il ne vouloit recevoir, et lui sembloit qu'il se fust pollue en conversant avec elle;” — “whom a little before he refused to receive, and seemed to him that he would be polluted by conversing with her.”;” — “whom a little before he refused to receive, and seemed to him that he would be polluted by conversing with her.”
