עָשָׂ֣ה יָ֭רֵחַ לְמוֹעֲדִ֑ים שֶׁ֝֗מֶשׁ יָדַ֥ע מְבוֹאֽוֹ׃
你造月亮以定節期；太陽知道自己沉落的時候。
Rashi
He made the moon for the appointed seasons To count with it the times and the festivals.
Rashi
the sun knows its setting But the moon does not know its setting, because sometimes it comes through a long way and sometimes it comes through a short way.
