Psalm 99:5-9 and Exodus 34:29-35

Psalm 99:5-9
5 Exalt the Lord our God, and adore the footstool of his feet, for it is holy.
6 Moses and Aaron are among his priests, and Samuel is among those who call upon his name. They called upon the Lord, and he heeded them.
7 He spoke to them in the pillar of the cloud. They kept his testimonies and the precept that he gave them.
8 You heeded them, O Lord our God. You were a forgiving God to them, though taking vengeance on all their inventions.
9 Exalt the Lord our God, and adore on his holy mountain. For the Lord our God is holy.
Exodus 34:29-35
29 And when Moses descended from Mount Sinai, he held the two tablets of the testimony, and he did not know that his face was radiant from the sharing of words with the Lord.
30 Then Aaron and the sons of Israel, seeing that the face of Moses was radiant, were afraid to approach close by.
31 And being called by him, they turned back, both Aaron and the leaders of the assembly. And after he had spoken to them,
32 all the sons of Israel also now came to him. And he instructed them in all the things that he had heard from the Lord on Mount Sinai.
33 And having completed these words, he placed a veil over his face.
34 But when he entered to the Lord and was speaking with him, he took it off, until he exited. And then he spoke to the sons of Israel all that had been commanded to him.
35 And they saw that the face of Moses, when he came out, was radiant, but he covered his face again, whenever he spoke to them.
