For Moses, he went through different stages of life, from adolescence to old age, full of experiences, experiences and cognition. Perhaps Moses is old, and his understanding of God has a new direction, and his views on himself and life are gradually accumulating.
Moses' last poem was also his parting words. In this poem, he compares God to a rock, a refuge that supports people's strength and times of crisis, and points out that God cares and protects _ voters just as he protects _ pupils. God is like an eagle mother who takes care of the young eagle. The purpose of stirring the nest is to train the young eagle to grow up and give him kindness training.
