יַרְתִּ֣יחַ כַּסִּ֣יר מְצוּלָ֑ה יָ֝֗ם יָשִׂ֥ים כַּמֶּרְקָחָֽה׃
He maketh the deep to boil like a pot; He maketh the sea like a seething mixture.
Rashi on Job
He makes the deep seethe like a pot Like a small bubbling pot, that quickly raises bubbles one after another, so does he cause the deep, which is large and deep, to seethe.
Rashi on Job
he makes the sea like a seething mixture Like a mixture of a concoction of spices, which is compounded and mixed, so does he make and mix the sea when he moves from his place.
