When God in wrath against Moses and Aaron vowed, "Therefore ye shall not bring this assembly into the land which I have given them," Moses forbore to implore God to do away with this sentence, acting in accordance with the percept, "Do not attempt to dissolve thy neighbor's vow in the moment he hath made it." Moses waited forty years before he approached God with the request to permit him to enter the promised land with Israel.
This occurred when he had received God's command to appoint Joshua as his successor, for he now perceived that God had actually resolved to execute His sentence. For although God had ten times decreed that Moses was to die in the desert, still Moses had not troubled much about it, even when the resolution had been sealed in the heavenly court. He thought: "How often did Israel sin, and yet, when I prayed for them, He annulled the punishment He had decreed; surely God should accept my prayer, if I-a man who never sinned-should pray to Him."
Moses had also a special reason for assuming that God had changed His determination concerning him, and would not permit him to enter the promised land, for he had been permitted to enter the part of Palestine lying on this side of the Jordan, the land of Sihon and of Og, and from this he reasoned that God had not irrevocably decreed punishment for him, and that it might therefore now be recalled He was strengthened in this assumption by the fact that after the conquest of the east-Jordanic region God revealed to him the instructions as to how the land was to be divided, and it seemed to him as if he were in person to carry out these instructions.
He was, however, mistaken, for shortly after these laws had been revealed to him, God informed him that he was to look upon the promised land from Mount Abarin, as he should never enter it.
