"PUT OFF THY SHOES FROM THY FEET:FOR THE PLACE WHERE THOU STANDEST IS HOLY GROUND"

"Then fled Moses at this saying, and was a stranger in the land of Madian, where he begat two sons.
And when forty years were expired, there appeared to him in the wilderness of mount Sina an angel of the Lord in a flame of fire in a bush.
When Moses saw it, he wondered at the sight: and as he drew near to behold it, the voice of the LORD came unto him,
Saying, I am the God of thy fathers, the God of Abraham, and the God of Isaac, and the God of Jacob. Then Moses trembled, and durst not behold.
Then said the Lord to him, Put off thy shoes from thy feet: for the place where thou standest is holy ground.
I have seen, I have seen the affliction of my people which is in Egypt, and I have heard their groaning, and am come down to deliver them. And now come, I will send thee into Egypt.
This Moses whom they refused, saying, Who made thee a ruler and a judge? the same did God send to be a ruler and a deliverer by the hand of the angel which appeared to him in the bush.
He brought them out, after that he had shewed wonders and signs in the land of Egypt, and in the Red sea, and in the wilderness forty years.
This is that Moses, which said unto the children of Israel, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear.
This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sina, and with our fathers: who received the lively oracles to give unto us:
To whom our fathers would not obey, but thrust him from them, and in their hearts turned back again into Egypt,
Saying unto Aaron, Make us gods to go before us: for as for this Moses, which brought us out of the land of Egypt, we wot not what is become of him.
And they made a calf in those days, and offered sacrifice unto the idol, and rejoiced in the works of their own hands."
Acts 7:29-41
