Once more God made allowance for the weakness and self-distrust of Moses, severely tried as he had been by his former failure to persuade Pharaoh (Exodus 5:1-5) and his recent rejection by the people of Israel (Exodus 6:9).
He made allowance, and raised his courage and his spirits by fresh promises, and by a call upon him for immediate action. The process of deliverance, God assured him, was just about to begin. Miracles would be wrought until Pharaoh's stubbornness was overcome.
He was himself to begin the series at once by casting his rod upon the ground, that it might become a serpent (Exodus 7:9). From this point Moses' diffidence wholly disappears. Once launched upon his Heaven-directed course, assured of his miraculous powers, committed to a struggle with the powerful Egyptian king, he persevered without blenching or wavering until success crowned his efforts.
