Acts 7:31 WBT

²⁹  Then Moses fled at this saying, and was a stranger in the land of Madian, where he begat two sons.

³⁰  And when forty years had expired, there appeared to him in the wilderness of mount Sina, an angel of the Lord in a flame of fire in a bush.

³¹  When Moses saw [it], he wondered at the sight; and as he drew near to behold [it], the voice of the Lord came to him,

³²  [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.

³³  Then said the Lord to him, Put off thy shoes from thy feet: for the place where thou standest is holy ground.
