“And knew her not till she had brought forth her firstborn son: and he called his name JESUS.”
Matthew 1:25 — Greek Interlinear
Church Fathers on Matthew 1:25
Life returned by the same entrance through which death had entered in. By Adam’s disobedience we were ruined, by Joseph’s obedience we all begin to be recalled to our former condition; for in these words is commended to us the great virtue of obedience, when it is said, 'And Joseph rising from sleep, did as the Angel of the Lord had commanded him.'
He not only did what the Angel commanded, but as he commanded it. Let each one who is warned of God, in like manner, break off all delays, rise from sleep, and do that which is commanded him.
'Took unto him' not took home to him; for he had not sent her away; he had put her away in thought only, and now took her again in thought.
