New Defender's Study Bible Notes
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.
