כִּ֤י ט֣וֹב סַ֭חְרָהּ מִסְּחַר־כָּ֑סֶף וּ֝מֵחָר֗וּץ תְּבוּאָתָֽהּ׃
이는 지혜를 얻는 것이 은을 얻는 것보다 낫고 그 이익이 정금보다 나음이니라
Rashi
where he lies is gold upon the mire This is a repeated clause. “Where he lies is gold,” refers to “rays of the sun”; “upon the mire” refers to “under him,” in the place where he is on the sand; this is the mire where he lies. It shines like precious gold, as it is stated (Song 3:10): “its couch of gold.” חָרוּץ is a type of gold, as it is stated (Prov. 8:19): “My fruit is better than gold (מחרוץ), yea than fine gold.” Where he lies—an expression of a couch for lying down, like (Song 3:10), “its couch (רפידתו) of gold.”
