When Jesus died on the cross He turned off the sun - Why?

Lk 23:34-45

34 Then Jesus said, “Father, forgive them, for they do not know what they do.”fn And they divided His garments and cast lots.

35 And the people stood looking on. But even the rulers with them sneered, saying, “He saved others; let Him save Himself if He is the Christ, the chosen of God.”

36 ¶ The soldiers also mocked Him, coming and offering Him sour wine,

37 and saying, “If You are the King of the Jews, save Yourself.”

38 ¶ And an inscription also was written over Him in letters of Greek, Latin, and Hebrew:

THIS IS THE KING OF THE JEWS.

39 ¶ Then one of the criminals who were hanged blasphemed Him, saying, “If You are the Christ, save Yourself and us.”

40 ¶ But the other, answering, rebuked him, saying, “Do you not even fear God, seeing you are under the same condemnation?

41 “And we indeed justly, for we receive the due reward of our deeds; but this Man has done nothing wrong.”

42 Then he said to Jesus, “Lord, remember me when You come into Your kingdom.”

43 ¶ And Jesus said to him, “Assuredly, I say to you, today you will be with Me in Paradise.”

Jesus Dies on the Cross

(Matt. 27:45-56; Mark 15:33-41; John 19:25-30 )

44 ¶ Now it was about the sixth hour, and there was darkness over all the earth until the ninth hour.

45 Then the sun was darkened, and the veil of the temple was torn in two.
