Midrasz do Królów II 13:7

"and they that turn the many to righteousness (will shine) as the stars forever": Just as the stars are high and exalted above all mortals, so, the righteous. And just as the light of the stars can be seen from one end of the world to the other, so, the light of the righteous. And just as the stars are sometimes revealed and sometimes concealed, so, the righteous. And just as there are innumerable "coteries" of stars, so, there are innumerable coteries of the righteous. If Israel do the will of the L-rd, they are like the stars; if not, they are like the dust. And thus is it written ((II Kings 13:7) "for the king of Aram had destroyed them and made them like the dust for threshing."
