Commentary for Job 28:16

It cannot be praised Heb. תסלה, an expression of (Ps. 68:5), “Extol Him (סלו) Who rides in Aravoth.” He who praises it saying, “It is as esteemed as the gold of Ophir and as precious onyx,”—this is no praise for it. Similar to this is (Lam. 4:2), “praised (המסלאים) with fine gold.”
