John Gill's Bible Commentary Ver. 9. For as yet they knew not the Scripture , etc.] Meaning not some particular passage of Scripture, but the writings of the Old Testament in general, and the various places in it, which spoke of the resurrection of Christ, either in a way of type, or prophecy; such as ( Genesis 22:3,4, 10:13, Jon 2:1-7, Psalm 16:10, Hosea 6:2, Isaiah 26:19) and though our Lord had often referred to some of them, at least as in ( Matthew 12:40, 16:21, 20:18,19) yet such was the dulness of the disciples, or such their prejudices in favour of the Messiah being to continue, and set up a temporal kingdom, that even John, who leaned on his breast, and Peter, who was so inquisitive and desirous of knowing our Lords meaning in everything, did not understand the sense of his words, nor of those places of Scripture he had reference to: that he must rise again from the dead : so it was determined, thus it was predicted, and the justification and salvation of Gods elect required it; and yet they knew not the thing, nor the necessity and importance of it.
Matthew Henry Commentary
Verses 1-10 - If Christ gave his life a ransom, and had not taken it again, it woul not have appeared that his giving it was accepted as satisfaction. It was a great trial to Mary, that the body was gone. Weak believers ofte make that the matter of complaint, which is really just ground of hope and matter of joy. It is well when those more honoured than others with the privileges of disciples, are more active than others in the duty of disciples; more willing to take pains, and run hazards, in a good work We must do our best, and neither envy those who can do better, no despise those who do as well as they can, though they come behind. The disciple whom Jesus loved in a special manner, and who therefore in special manner loved Jesus, was foremost. The love of Christ will make us to abound in every duty more than any thing else. He that was behin was Peter, who had denied Christ. A sense of guilt hinders us in the service of God. As yet the disciples knew not the Scripture; the Christ must rise again from the dead.
