Exodus 40:27

And he burnt sweet incense thereon
Which is another branch of the priestly office exercised by Moses, and which he would never have done had he not had a command from God for it, as follows:

as the Lord commanded Moses;
he commanded Moses indeed to order and direct Aaron to do this, but he being not yet consecrated, Moses, being the Lord's priest, did it.
