Exodus 33:
19 And the LORD said, “I will cause all my goodness to pass in front of you, and I will proclaim my name, the LORD, in your presence. I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. 20 But,” he said, “you cannot see my face, for no one may see me and live.”
21 Then the LORD said, “There is a place near me where you may stand on a rock. 22 When my glory passes by, I will put you in a cleft in the rock and cover you with my hand until I have passed by. 23 Then I will remove my hand and you will see my back; but my face must not be seen.”
I agree that Moses wanted to see His glory, but look what God said in return
God had to be veiled in the pillar of cloud for Moses can talk to God face to face.
To see His face without a veil is to see His glory, as we see God through Jesus with unveiled faces and live.
You are completely ignoring verse 11.
Exo 33:11 And the LORD spake unto Moses
face to face, as a man speaketh unto his friend. And he turned again into the camp: but his servant Joshua, the son of Nun, a young man, departed not out of the tabernacle.
This was said in verse 11 before Moses requested to see his glory in verse 18.
It was only after God agreed to show Moses "all my goodness" that God told Moses he could not see his face.
Exo 33:19 And he said,
I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
20 And he said,
Thou canst not see my face: for there shall no man see me, and live.
So, verse 20 does not negate verse 11. There was a reason now that Moses could not see God's face, God was going to reveal his glory, all his goodness to Moses. This is similar to when Jesus showed himself to the disciples on the mount of transfiguration. Had they seen Jesus's face before? YES.
And, as I showed in Chapter 34, it says Moses always took his vail off before he entered the tabernacle and spoke with God.
Exo 34:28
And he was there with the LORD forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the covenant, the ten commandments.
29 And it came to pass, when Moses came down from mount Sinai with the two tables of testimony in Moses' hand, when he came down from the mount, that Moses wist not
that the skin of his face shone while he talked with him.
30 And when Aaron and all the children of Israel saw Moses,
behold, the skin of his face shone; and they were afraid to come nigh him.
31 And Moses called unto them; and Aaron and all the rulers of the congregation returned unto him: and Moses talked with them.
32 And afterward all the children of Israel came nigh: and he gave them in commandment all that the LORD had spoken with him in mount Sinai.
33
And till Moses had done speaking with them, he put a vail on his face.
34
But when Moses went in before the LORD to speak with him, he took the vail off, until he came out. And he came out, and spake unto the children of Israel that which he was commanded.
35
And the children of Israel saw the face of Moses, that the skin of Moses' face shone: and Moses put the vail upon his face again, until he went in to speak with him.
Nowhere does it say that God had a vail on his face, that is an assumption on your part not supported by scripture. Moses face shone because he was speaking to God face to face as a friend. When Moses appeared before the people he had to wear a vail, but whenever he went into the tabernacle to speak to God he took the vail off.
You can believe what you want, but Exo 33:11 says Moses spoke to God face to face.
And, as I showed earlier, Abraham saw God.
Gen 18:1
And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
2
And he lift up his eyes and looked, and, lo, three men stood by him:
and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
3 And said, My Lord, if now I have found favour in thy sight, pass not away, I pray thee, from thy servant:
This is simple and straightforward, verse 1 says the Lord "appeared" to Abraham. Verse 2 says he "lift up his eyes and looked" and when he "saw them". One of these three men was the Lord, as Abraham says in verse 3.
Pretty hard to ignore the language used, "appeared" "eyes" "looked" "saw". I don't see how anyone can deny that Abraham did not literally see the Lord.
