New Defender's Study Bible Notes
3:13 thine anointed. “Thine anointed” is referring to “Thy Messiah” or “thy Christ.” This passage surely must refer to the return of Christ in glory “for the salvation of thy people.”
3:13 the head. The phrase, “head out of the house of the wicked,” if taken literally must refer to the coming Man of Sin who will rule over all nations for a brief time in the last days. Even more directly, it seems to refer to Satan, who will energize and indwell the Man of Sin. When Christ returns, “He shall smite the earth with the rod of His mouth, and with the breath of His lips shall He slay the wicked” (Isaiah 11:4). “Then shall that Wicked [One] be revealed, whom the Lord shall consume with the Spirit of His mouth, and shall destroy with the brightness of His coming” (II Thessalonians 2:8). He shall fatally “bruise thy head,” as God told Satan long ago in the garden of Eden (Genesis 3:15).
