Exodus 34:34

But when Moses went in before the Lord to speak with him,
&c.] Went into the tabernacle to converse with him, to pray unto him, and inquire about any matter of difficulty respecting the people of Israel he was concerned for, which he often did:

he took the vail off until he came out:
and so when men are truly converted, and turn to the Lord, the vail of darkness and unbelief is removed, and the true light shines, in which they see things in another light than they did before; and when they come into his presence, they come with hearts opened and unveiled, all things being naked and open to him with whom they have to do; and particularly saints under the Gospel dispensation, with an open face, as in a glass, behold the glory of the Lord; and when they get to heaven, they will then see face to face, and know as they are known, ( 2 Corinthians 3:16 2 Corinthians 3:18 ) ( 1 Corinthians 13:12 ) :

and he came out, and spake unto the children of Israel [that] which
he was commanded;
this respects not the present time of his coming down from the mount, or out of the tabernacle with the law and commands now given, for these he had already declared; but after times, and all such times when he went in to the Lord to inquire of him his mind and will concerning certain things, in which the people wanted information, when, upon his return, he acquainted them with whatsoever the Lord ordered to be done.
