Rabbi Nehorai said: It is the decree of the King that when Israel sins || and fails to intercalate the year as is becoming, the Holy One, blessed be He, acts in His mercy at the time when the flame of the sun reaches the moon by night at 40 degrees (or ascents), then the Holy One, blessed be He, makes the moon dim and hides one of the Synhedrion. When Israel does the will of the Holy One, blessed be He, in His great mercy He makes the sun dim and He sends forth His anger upon the nations of the world, as it is said, "Thus saith the Lord, Learn not the way of the nations, and be not dismayed at the signs of heaven, for the nations are dismayed at them" (Jer. 10:2).
Just as the moon's light does not rule over the sun's light by day, nor does the sun's light rule over the moon's light by night, likewise the calculation of the moon does not rule by day nor does the calculation of the sun (obtain) by night, and the one does not trespass on the boundary of the other.
