Why were the heads of Israel supposed to be brought together before the exodus?
The heads of Israel were assembled so that God could announce to them that the time of their deliverance was at hand. This gathering prepared the people’s leaders to receive the message that God was about to move on their behalf and bring them out of Egypt.
Les explains that the heads of the people were to be brought together so that God could announce to them that the time of their deliverance was at hand. This announcement came after God revealed Himself to Moses as the I Am and as the God of Abraham, Isaac, and Jacob. God also told Moses that the king of Egypt would not let Israel go, and that He would stretch out His hand and smite Egypt with all His wonders; after that, the king would let them go.
