And Moses called unto them,.... Who, as it appears by what follows, on sight of him were so terrified, that they did not proceed on to meet him, but went back, and therefore he called unto them to return and come forward: and Aaron and all the rulers of the congregation returned unto him; knowing him by his voice, and encouraged by his call of them, who before might take him to be something more than human, some glorious form, one of the heavenly angels appearing in this manner: and Moses talked with them; after he had put a vail on his face, of which there is an account in the following verses. He talked with them friendly, and told them all that had happened to him in the mount; what a glorious sight he had been indulged with; what a proclamation of the grace and goodness of God had been made to him; and what laws and ordinances God had enjoined him and them the observance of.
