Ephesians
King James Version (KJV)

“Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.”
King James Version (KJV)
5:14 Wherefore he - God. Saith - In the general tenor of his word, to all who are still in darkness. Awake thou that steepest - In ignorance of God and thyself; in stupid insensibility. And arise from the dead - From the death of sin. And Christ shall give thee light - Knowledge, holiness, happiness.
Eph 5:14 Wherefore he saith. Who says, or where, is uncertain. There is a similar thought in Isa 60:1,2 26:19. He probably means that God, in substance, says. Awake thou that sleepest. The sleeper represents one not converted. Arise from the dead. From death in sin (Eph 2:1). Conversion is often described as a spiritual resurrection (Ro 6:4-6 Col 2:12). And Christ. Christ gives light to all who come to him. The Greek quotation is in verse, and has been translated, Sleeper, awake; rise from the dead, And Christ on thee his light shall shed.
