Rashi
Under him are rays of the sun in the place he rests, there are rays of the sun, because his fins, which are under him on his belly, illuminate and shine like the sun.
Rashi
rays Heb. חדודי, like a sharp sword, which is sharpened, bright, and whitened. Because of this, he calls rays חַדוּדֵי.
Rashi
sun Heb. חרשׂ, the sun, like (above 9:7), “He who spoke to the sun (לחרס) and it did not shine”; (Jud. 14:18); “before the sun (החרסה) set. “
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.”
