And Moses rose up, and his minister Joshua,.... In order to go up higher on the mount. Joshua, and he only, was to go up higher with him, though not to the top of the mount, at least not into the cloud upon it, as Moses did.
Joshua was his minister or servant, and waited upon him wherever he went, and was to be his successor; and therefore for his encouragement, and to qualify him the better for it, he was indulged with a sight and knowledge of things others were not; for by his not knowing anything of the idolatry of the golden calf, Ex 32:17 it appears that he was on some part of the mount all the forty days and forty nights; and if it should be asked whether he fasted all that time, or, if he did not, how he was provided with food and drink?
