Numbers 22:20-21

If the men come to call thee, rise up and go with them He had no leave to go at all unless the messengers came again in the morning to him. And, perhaps, if he had not gone to them, after having promised them an answer, they might have thought their master's great offers neglected, and have gone away without him. But his head and heart were too full of expectations from the journey, to run the hazard of not being further invited into it. And so he rose early in the morning, and saddled his ass Or commanded it to be saddled, for he had servants to wait upon him; and went to them, directly contrary to God's express order, and was opposed by the angel for the breach of his duty.
