Right hand, man of the
'The man of the right hand,' as in Psalm 80:17, signifies the Lord with respect to the Word. He is called 'the man of the right hand,' because the Lord has power by divine truth, which is the Word. He had the divine power itself when He fulfilled the whole Word. So He also said that, 'they should see the soul of a person sitting in power, on the right hand of the Father!'
