תענית ט״ו א:ב׳
Rav Naḥman bar Yitzḥak said: I too say a similar idea. Not all are fit for light, and not all are fit for gladness. The righteous are fit to be rewarded with light, and the upright are fit to be rewarded with gladness. The righteous are fit to be rewarded with light, as it is written: “Light is sown for the righteous” (Psalms 97:11), and the upright are fit to be rewarded with gladness, as it is written, in the same verse: “And gladness for the upright in heart.”
