‘And Miriam was shut up outside the camp seven days, and the people journeyed not till Miriam was brought in again.'
So Miriam was made an outcast from the camp for seven days, after which she was allowed in again. It could hardly go unnoticed. All would know that she had been stricken by Yahweh, even if the reason for it was only rumoured. They would see her here excluded from the camp and rumour would be rife. But at least, because of Moses' intercession, it was only temporary.
Miriam's status among the people comes out in the fact that they were ready to wait for her return to the camp before proceeding, and that Moses could expect them to.
