Wrath = land darkened, thus land is darkened on the cross. In a little wrath he hides his face, Jesus asks why hast thou forsaken me? Job says it can be done against a nation or a man, and Jesus died for the nation. And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
Says this also
Isaiah 53:10 Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.
It's interesting that Matthew leaves this cry in Aramaic;
the translation I've read directly from the Aramaic is
"My God, my God for this was I kept."
Then take a look at the Psalm Christ is quoting:
"O God, my God, hear me; why have you forsaken me ?
The words of my transgressions are far from my salvation.
O my God, I will cry out by day, but you will not hear me;
And by night, but not for understanding in me." (LXX)
"My God, my God, why have you forsaken me; why so far from saving me, from the words of my roar ? O my God ! I call out by day, but you answer me not; and by night, but there is no respite for me." (Masoretic)
When did God refuse to hear Jesus ?
Who is Christ speaking for on the cross ? For His benefit, or ours ? On behalf of Himself, or those He came to save ?
To read the Psalm in full, it begins with the despair of mankind in the state of separation from God, and then proceeds with a prophetic recounting of the crucifixion, and ends with the joy of restoration (including the gentiles) to God.
God cannot abandon Himself; Jesus Christ is God, the Son of God incarnate. He humbled Himself voluntarily for us, and even to crucifixion
on our behalf/
toward our salvation.
In case there is any doubt of His purpose, Christ speaks the opening lines of the Psalm which evokes (or should) the rest of it.
