New Defender's Study Bible Notes
22:29 not knowing the scriptures. The Sadducees, who rejected the doctrine of resurrection, thought they could embarrass Jesus with their silly question of a woman who had married seven brothers successively. But all those who think they can find mistakes or contradictions in the Bible simply show that they know neither the Scriptures nor God’s power.
22:30 given in marriage. Almost every person is a member of at least two families on earth, that of his parents plus that of his own spouse and children. Some, of course, have more than one spouse, if the first spouse dies and he or she marries again. There is no way that our present relationships can continue unchanged after the resurrection, however, all will enjoy rich fellowship with the entire “family of God,” the redeemed children of Mother Eve.
22:31 have ye not read. Although this statement was spoken specifically by God to Moses (Exodus 3:6), all Scripture is inspired by God and can be considered by each person as directly “spoken unto you by God.”
22:32 I am the God. With a single word from the Old Testament (“am” rather than “was,” stressing the tense of the verb), the Scripture, as cited by Christ, both confirms the truth of life after death, rebukes the Sadducean priests, and illustrates the vital importance of the doctrine of the verbal (word-by-word, rather than general concepts) inspiration of the Bible. Note also Matthew 5:18; 22:45.
