Matthew 27:46Now from the sixth hour there was darkness over all the land until the ninth hour. And about the ninth hour Jesus cried out with a loud voice, saying, Eli, Eli, lema sabachthani? that is, My God, my God, why have you forsaken me?
Matthew wrote, "that is ...". Matthew interpreted or translated the words, 'lema sabachthani', to "mean, why have you forsaken me?"
So what did Matthew mean with the word, --Greek, 'enkatélipes' - 'enkataleípoh'? ‘en’ – in / with; ‘katá’ – in virtue of / in proportion to; ‘leípoh-leípos’ – remainder / henceforth / finally; ‘katáloipos’ – legacy / remnant / remaining (chadal Gn42:33 yathar Is1:9 Ez12:16) “The rest of the blood he shall poor out at the bottom of the altar a sin offering” Lv5:9/10.
I believe the translation with ‘forsake’ was unfortunate. The word is normally rendered, to ‘leave’. Jesus was given command --was given 'leave'-- to do the will of God, and to empty the cup of his suffering. He actually prayed the Father, “not my will (which was “to do Thy will, o God”) but Your will be done” in the end or climax. And Jesus PRAYED the Father that He might glorify the Father, and the Father might glorify Him. Even though it was Jesus' own will, He would have his will be his Father’s will. So now here Jesus is facing the full reality of the crisis of the cross, ‘YOUR will shall be done, my Father; THIS IS my hour, come, glorify Yourself in Me, fully.’ And the only way to glorify Himself for the Father is to “leave” the Son to do his will, perfectly.
I understand more a ‘sanctification’ by the Father of the Son in this Scripture. He put the Son apart for holy purpose and end. “Why” or ‘What have you sanctified Me for, my Father? For that which I prayed you, for: “Not my will, but YOUR will, be done.”
Jesus spoke with his Father; He gave his life into his Father's hands --- how could there have come a separation, one of abandonment, a forsaking of Jesus by the Father? Not at all! In fact, when Jesus had died, at that very moment in time, the veil which covered the Shekinah of God's Presence from human gaze, was torn in two from the top to the bottom ... and God's Presence LEFT THE TEMPLE and would on the cross and afterwards in Joseph's grave, go "COVER" the body of Jesus so that "his flesh would see no corruption in death", and He would be "in Thy sight always" / “before thy face always", "always" even in death!. “Thou shalt hide them in the secret of thy Presence from the pride of man,” Ps31:20 “my times in thy hand” Ps31:15 “Thou hast brought up my soul FROM THE GRAVE.” Ps30:3 “In the time of trouble He shall hide Me in his pavilion: in the secret of his tabernacle shall He hide me..” Ps27:5.
The darkness was the "Shadow"--'shekina'--"Presence of the Almighty" Psalm 91:1 and when Jesus died, daylight set in again. While Jesus still lived, He for no moment was 'forsaken' by his Father ---on the contrary.
Then after Jesus had died and daylight for Him had become darkness, the Presence of the Almighty for Him became Light. Exodus 14:20; 16:10; 19:9. It was the Passover-Suffering of Yahweh. Job 3:6.
