But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying,

People's New Testament

22:31 As touching the resurrection of the dead. The Sadducees doubted some of the prophetic books, but accepted Moses; hence, the Lord appeals to Moses to show that he taught future existence, or the resurrection, which is the sense in which the latter phrase is used.

Wesley's Notes

22:31 Have ye not read - The Sadducees had a peculiar value for the books of Moses. Out of these therefore our Lord argues with them.

Matthew Henry's Concise Commentary

22:23-33 The doctrines of Christ displeased the infidel Sadducees, as well as the Pharisees and Herodians. He carried the great truths of the resurrection and a future state, further than they had yet been reveled. There is no arguing from the state of things in this world, as to what will take place hereafter. Let truth be set in a clear light, and it appears in full strength. Having thus silenced them, our Lord proceeded to show the truth of the doctrine of the resurrection from the books of Moses. God declared to Moses that he was the God of the patriarchs, who had died long before; this shows that they were then in a state of being, capable of enjoying his favour, and proves that the doctrine of the resurrection is clearly taught in the Old Testament as well as in the New. But this doctrine was kept for a more full revelation, after the resurrection of Christ, who was the first-fruits of them that slept. All errors arise from not knowing the Scriptures and the power of God. In this world death takes away one after another, and so ends all earthly hopes, joys, sorrows, and connexions. How wretched are those who look for nothing better beyond the grave!
