ISB ~ Mark 12 v26

I am the God:Since the Sadducees restricted biblical authority to the Pentateuch, Jesus deliberately draws from the Pentateuch to demonstrate the resurrection (Ex 3:6).

• The passage narrates how Yahweh revealed himself to Moses at the burning bush as the God of the deceased patriarchs: Abraham, Isaac, and Jacob. Their intimacy with God even after death proves the immortality of their souls (Wis 3:1) and so hints at the future resurrection of their bodies (Is 26:19). See note on Mk 12:18.
