Hast thou entered into the springs of the sea? - Of these springs, inlets, or outlets of the sea, we know just as much as Job. There was prevalent among philosophers an opinion, that through a porous bottom fresh matter was constantly oozing by which the sea was supplied with new materials. But through such pores these materials might as well ooze out as ooze in.

Walked in the search of the depth? - Hast thou walked from the shallow beach through the great ocean's bed, till thou hast arrived at its profoundest depths? In other words, Dost thou know the depths of the sea? Job, we may presume, did not. No man since him has found them out. In multitudes of places they are unfathomed by any means hitherto used by man.

Whether it is Proper to the Rational Nature to be Adopted?
Objection 1: It would seem that it is not proper to the rational nature to be adopted. For God is not said to be the Father of the rational creature, save by adoption. But God is called the Father even of the irrational creature, according to Job 38:28: "Who is father of the rain? Or who begot the drops of dew?" Therefore it is not proper to the rational creature to be adopted. Objection 2: Further, by reason of adoption some are called sons of God. But to be sons of God seems to be properly attributed …

'The End of the Lord'
'Then Job answered the Lord, and said, 2. I know that Thou canst do every thing, and that no thought can he withholden from Thee. 3. Who is he that hideth counsel without knowledge? therefore have I uttered that I understood not; things too wonderful for me, which I knew not. 4. Hear, I beseech Thee, and I will speak: I will demand of Thee, and declare Thou unto me. 5. I have heard of Thee by the hearing of the ear: but now mine eye seeth Thee. 6.
