The Greek word “Koimao” used here for sleep means deceased or dead! Jesus goes on in a later verse to emphasize that Lazarus is dead! There is another Greek word used for sleep in the New Testament which is “Katheudo.” This word means to lie down and rest but was not used in this passage of scripture. What may be of interest to you is this same Greek word used for sleep which means deceased or dead is the same word used in Acts 12:6. Peter was sleeping between two soldiers in chains! Verse 7; The Angel of the Lord came upon him and light shone in the prison and smote Peter on the side and raised him up, saying arise up! His chains fell off! Herod had Peter beaten badly! By definition of the word used Peter could have been deceased lying between the two soldiers! Peter may have been raised from the dead! The angel was probably Jesus Himself! The events recorded in our Bible are important to our Faith so I make an effort to go back to the original languages to see greater detail! James and Hamsa Sasse. GodWhoisGod.com
