Matthew Henry on Deuteronomy 34:1-4

Moses seemed unwilling to leave his work; but that being finished, he manifested no unwillingness to die. God had declared that he should not enter Canaan. But the Lord also promised that Moses should have a view of it, and showed him all that good land. Such a sight believers now have, through grace, of the bliss and glory of their future state. Sometimes God reserves the brightest discoveries of his grace to his people to support their dying moments. Those may leave this world with cheerfulness, who die in the faith of Christ, and in the hope of heaven.
