Only the Gospel of Mark mentions the arms of the Lord Jesus.
Mark 9:36 And He took a child, and set him in the midst of them: and when He had taken him in His arms, He said unto them,
Mark 10:16 And He took them up in His arms, put His hands upon them, and blessed them.
Amazing to think, that the Gospel of Mark presents the busy Servant of Jehovah, and to think, that He has time to stop and embrace children!
