Danker, 2000, (pp. 576-577) lists Mark 5:19 under the definition of “lord” as “a designation of God.” It goes on to say concerning the use of the expression in the Septuagint [LXX]: “It freq. [frequently] replaces the name Yahweh in the MT [Masoretic Text].”

The Gospel According to St. Mark: The Greek Text With Introduction, Notes, and Indexes, by Vincent Taylor, 1952, on page 285 says that this occurrence of Kyʹri·os (Lord) “is used of God.”

In his book The Gospel According to Mark, 1858, Joseph Addison Alexander expresses his opinion that the “ambiguous expression,” “the Lord,” in this verse describes Christ. However, he goes on to acknowledge that “the hearers may have understood [this expression] more vaguely, as denoting God, perhaps with special reference to his covenant relations with his people, as expressed by the Hebrew name Jehovah, for which the constant equivalent or rather substitute both in the Septuagint and the New Testament is (ὁ κύριος) the Lord.”

The Gospel According to St. Mark: The Greek Text With Introduction, Notes, and Indexes, by Vincent Taylor, 1952, on page 514 says of this occurrence of Kyʹri·os (Lord) in the Greek text: “Here the idea found in many apocalyptic writings, that in His mercy and for the sake of the elect God has shortened the period of tribulation for mankind . . . is strongly expressed.” Taylor goes on to say on page 515: “The use of the anarthrous Κύριος is characteristic of [Old Testament] quotations.”

In his expositional commentary The Gospel of Mark, 1994, (p. 378) D. Edmond Hiebert makes this comment on Mark 13:20: “The Lord, Jehovah God of the Old Covenant, is in sovereign control of the affairs of this world, and He has graciously decreed a limitation on those days.”
