Charles Ellicott Commentary Mark 16:19-20

"So then the Lord Jesus, after he had spoken unto them, was received up into heaven, and sat down at the right hand of God. And they went forth, and preached everywhere, the Lord working with them, and confirming the word by the signs that followed. Amen." — Mark 16:19-20 (ASV)

So then after the Lord had spoken.—See Note on Luke 24:53. St. Matthew, it will be remembered, gives no account of the Ascension. (See Note on Matthew 28:20.) St. Mark and St. Luke record it briefly. St. John implies it in his report of our Lord’s words (John 6:62; John 20:17). In Acts 1:3-11 it is narrated with greater fullness.

The form of the last two verses, the use of the “Lord” instead of Jesus, suggests the thought of their being a later addition to the original records of our Lord’s life and teaching. (See Note on Luke 7:13.)
