Zechariah 14:6-9

On that day the sources of light will no longer shine, yet there will be continuous day! Only the LORD knows how this could happen. There will be no normal day and night, for at evening time it will still be light. On that day life-giving waters will flow out from Jerusalem, half toward the Dead Sea and half toward the Mediterranean, flowing continuously in both summer and winter. And the LORD will be king over all the earth. On that day there will be one LORD—his name alone will be worshiped.
