10 For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine.
23 Then the moon shall be confounded, and the sun ashamed, when the Lord of hosts shall reign in mount Zion, and in Jerusalem, and before his ancients gloriously.
19 The sun shall be no more thy light by day; neither for brightness shall the moon give light unto thee: but the Lord shall be unto thee an everlasting light, and thy God thy glory.
20 Thy sun shall no more go down; neither shall thy moon withdraw itself: for the Lord shall be thine everlasting light, and the days of thy mourning shall be ended.
10 The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:
11 And the Lord shall utter his voice before his army: for his camp is very great: for he is strong that executeth his word: for the day of the Lord is great and very terrible; and who can abide it?
15 The sun and the moon shall be darkened, and the stars shall withdraw their shining.
16 The Lord also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the Lord will be the hope of his people, and the strength of the children of Israel.
24 But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,
25 And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.
26 And then shall they see the Son of man coming in the clouds with great power and glory.
29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
49 And so great shall be the glory of his presence that the sun shall hide his face in shame, and the moon shall withhold its light, and the stars shall be hurled from their places.
33 And immediately after the tribulation of those days, the sun shall be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of heaven shall be shaken.
34 Verily, I say unto you, this generation, in which these things shall be shown forth, shall not pass away until all I have told you shall be fulfilled.
35 Although, the days will come, that heaven and earth shall pass away; yet my words shall not pass away, but all shall be fulfilled.
36 And, as I said before, after the tribulation of those days, and the powers of the heavens shall be shaken, then shall appear the sign of the Son of Man in heaven, and then shall all the tribes of the earth mourn; and they shall see the Son of Man coming in the clouds of heaven, with power and great glory;
If you want to know about the time when the sun and moon are to be darkened, and when the stars will no longer give any light, and when there will be total darkness over all the face of the earth, here is an event predicted so that you cannot mistake. When you see the nations of the earth, especially the heathen nations, and also those north of Jerusalem–the great nation of Russia and other nations on the continent of Asia, together with many in Europe, gather up against Jerusalem after the Jews have returned and rebuilt their city and Temple, and when their armies become exceeding great multitudes in the valley of decision, then you may look for the Lord to come down with his mighty ones, and for the constellations of heaven to be darkened.
