This extended encounter and dialogue between God and Moses is full of meaningful content. The God who reveals Himself to Moses is the same God of the patriarchs (3:6.14-15). He cares about the situations of the weak and marginalized. Moses—and humanity—approach Him with respect: he must remove his sandals and cover his face in a gesture of reverence. Verses 7-15 describe Moses’ call and the mission he is given. They also reveal the intimate nature of God (3:7f).
This revelation gained new significance during the Israelite exile in Babylon (587-536 B.C.). Here’s the Good News: the god or gods who justified the pharaoh’s oppression and policies are unrelated to the God of justice and freedom; “I am” is the God who rescues, the God who risks everything for the life and freedom of his oppressed people.
