Êxodo 4

Êxodo 4:6-7
Again, another sign which Moses gave points to our Lord Jesus Christ. He put his hand into his bosom and drew it out again, and his hand had become as snow. A second time he put it in and drew it out, and it was again like the appearance of human flesh. This signified first the original glory of the Godhead of the Lord Jesus and then the assumption of our flesh, in which truth all nations and peoples must believe. So he put in his hand, for Christ is the right hand of God; and whosoever does not believe in his Godhead and incarnation is punished as a sinner; like that king who, while not believing open and plain signs, yet afterwards, when punished, prayed that he might find mercy. — On the Duties of the Clergy 3.15.95
Êxodo 4:12
The Lord also said to the Apostles, opening their mouths, Receive ye the Holy Ghost, whereby He declared that He is the same Who said to Moses, I will open thy mouth, and teach thee what thou shalt say. Wherefore this wisdom, divine, unspeakable, unadulterated and incorruptible, pours her grace into the minds of her saints, and discloses to them knowledge that they may behold her glory. — Letter 65.4
