פירוש על ישעיהו 60:20

neither...be gathered in Heb. יֵאָסֵף, an expression similar to (Joel 2:10) “gathered in (אָסְפוּ) their brightness.” Gathered in their light.

Thy sun shall no more go down, etc. That sun¹⁹The glory of the Lord mentioned in the preceding verse as a substitute for the light of sun and moon. will not set, and that moon לא יאסף Shall not withdraw itself. Lit., shall not be gathered; the moon appears dark to the earth, when in conjunction with the sun.²⁰The phrase the moon is gathered means, according to I. E., the moon comes together with the sun, in one straight line from the earth, so that the part of the moon illuminated by the sun is not seen by the inhabitants of the earth, and she is, therefore, not seen at all: this is the case at every new moon.

And the days of thy mourning shall be ended. The mourner sits, as it were, in darkness.
