Verse 17
How precious also are thy thoughts - רעיך reeycha, thy cogitations; a Chaldaism, as before.
How great is the sum of them! - מה עצמו ראשיהם mah atsemu rasheyhem; How strongly rational are the heads or principal subjects of them! But the word may apply to the bones, עצמות atsamoth, the structure and uses of which are most curious and important.
