Theophylact of Ohrid
Catena Aurea · Lukasevangelium 24
And he led them out as far as to Bethany, and he lifted up his hands, and blessed them. And it came to pass, while he blessed them, he was parted from them, and carried up into heaven. And they worshipped him, and returned to Jerusalem with great joy: And were continually in the temple, praising and blessing God. Amen.
Perhaps pouring into them a power of preservation, until the coming of the Spirit; and perhaps instructing them, that as often as we go away, we should commend to God by our blessing those who are placed under us.
