Did God appear to any humans in the Old Testament? Part 2 (48)

#48 Did the true God, Yahweh, appear to any human beings in the Old Testament period from the time of the Book of Genesis to the Book of Malachi? (A sequel of the immediately preceding question.)

Answer:  Let us note several passages and define some terms:

Passages: 

Isaiah 6:1-5, “In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew.  And one cried to another, and said: ‘Holy, holy, holy, is the LORD  of hosts; the whole earth is full of His glory!’ And the posts of the door were shaken by the voice of him who cried out, and the house was filled with smoke. Then I said: ‘Woe is me, for I am undone! Because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts.’”

Isaiah 46:3, “Listen to Me, O house of Jacob, and all the remnant of the house of Israel, who have been upheld by Me from birth, who have been carried from the womb: even to your old age, I am He.”

Isaiah 63:1, “Who is this who comes from Edom, with dyed garments from Borzrah, this One who is glorious in His apparel, traveling in the greatness of His strength?”

Zechariah 2:8, “For thus says the LORD of hosts, ‘He sent Me after glory, to the nations which plunder you; for he who touches you touches the apple of His eye.’”
