A mini history of Israel from Jacob to David to be told from generation to generation so that all will know of God’s wonderful deeds, will trust in God and obey Him.
The miracles in Egypt – plagues, dividing the sea. The miracles in the desert – food and water and direct guidance.
When God punished, they would return to Him, but usually only in lip service, not truly in their hearts. Even so, God was always merciful and forgiving.
