Acts 7:54

Now when they heard these things, they were cut to the heart, and they gnashed on him with their teeth. But he, being full of the Holy Spirit, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God, and said, Behold, I see the heavens opened, and the Son of man standing on the right hand of God.

Gnashed on him with their teeth ... does not mean that they bit or chewed upon Stephen's flesh but that they were so infuriated that they ground their teeth together in a rage.

Saw the glory of God ... It was fitting indeed that God should have given to the first Christian martyr such a glorious vision of eternal realities.

Jesus standing on the right hand of God ... As Hervey said:

Sitting at the right hand of God is the usual attitude ascribed to our Lord in token of his victorious rest, and waiting for the day of judgment; but here he is seen standing, as rising to welcome his faithful martyr, and to place on his head the crown of life.[19]

Son of man ... Only here, in the word of God, is there the use of this title for Jesus except in his own words concerning himself.
