The Angel Of His Presence

Isaiah 63:7-9 ESV
The Lord's Mercy Remembered
7 I will recount the steadfast love of the Lord,
the praises of the Lord,
according to all that the Lord has granted us,
and the great goodness to the house of Israel
that he has granted them according to his compassion,
according to the abundance of his steadfast love.
8 For he said, “Surely they are my people,
children who will not deal falsely.”
And he became their Savior.
9 In all their affliction he was afflicted,
and the angel of his presence saved them;
in his love and in his pity he redeemed them;
he lifted them up and carried them all the days of old.

John refers to the angels of churches in Revelation. The angel of His presence was present in each place, a light on a lampstand holding out the light of God.
