Helaman 14:20

But behold, as I said unto you concerning another sign, a sign of his death: behold, in that day that he shall suffer death, the sun shall be darkened and refuse to give his light unto you; and also the moon, and the stars; and there shall be no light upon the face of this land, even from the time that he shall suffer death, for the space of three days, to the time that he shall rise again from the dead;

“As I said, here is another sign of his death. On the day he dies, the sun will get dark. It will not give you light. The moon and stars won’t give light either. There will be no light on this land. This will last three days. It will start when he dies. It will end when he rises from the dead.”

“Now, about that other sign I mentioned—the sign of his death: On the day he dies, the sun will go dark and refuse to give you light. The moon and stars too. No light will shine on this land from the moment he dies until three days later when he rises from the dead.”
