1 Corinthians 13:10

But when that which is perfect is come,.... When perfect knowledge of God, of Christ, and of the mysteries of the kingdom of heaven shall take place; which will not in this life, but in that which is to come. So the Jews say r that at the resurrection, upon the reunion of the soul and body,

"the children of men shall attain to דעה שלימה, "perfect knowledge";''

which is what the apostle refers to here:

and then that which is in part, shall be done away: the imperfection of knowledge shall be removed; the imperfect manner of communicating knowledge, and of receiving and acquiring it, will cease: thus the apostle explains what he means by the cessation and failing of knowledge, and prophecy; not that knowledge itself will be no more, and a state of ignorance and darkness succeed; but imperfect knowledge will vanish away, or rather will be perfected, or be swallowed up in perfect knowledge; the imperfection of it will disappear; and it will be no more taught and received in part; the whole of truth will be clearly known.
