Charles Ellicott Commentary Mark 5:19

"And he suffered him not, but saith unto him, Go to thy house unto thy friends, and tell them how great things the Lord hath done for thee, and [how] he had mercy on thee." — Mark 5:19 (ASV)

The Lord hath done for thee.—Coming from our Lord’s lips, and having “God” as its equivalent in Luke 8:39, the word “Lord” must be taken in its Old Testament sense, as referring, not to the Lord Jesus, but to the Father.
