Verse 6. - Whereupon are the foundations thereof fastened? These details follow naturally upon the adoption of the particular metaphor of a house or building. They are not to be pressed. The object is to impress on Job his utter ignorance of God's ways in creation. Or who laid the corner-stone thereof? Who gave the last finishing touch to the work (see Psalm 118:22; Zechariah 4:7)? Canst thou tell? If not, why enter into controversy with the Creator?

38:4-11 For the humbling of Job, God here shows him his ignorance, even concerning the earth and the sea. As we cannot find fault with God's work, so we need not fear concerning it. The works of his providence, as well as the work of creation, never can be broken; and the work of redemption is no less firm, of which Christ himself is both the Foundation and the Corner-stone. The church stands as firm as the earth.Whereupon are the foundations thereof fastened?.... Or the pillars of it, as Ben Gersom interprets it; see Psalm 75:3; and which Aben Ezra understands of the mountains: but be they what they may, on what can they be fastened or sunk into, when the earth hangs on nothing, and there is nothing visible to support it, nothing but the mighty hand of God?

or who laid the corner stone thereof? which unites, cements, and keeps the fabric together, and is the ornament and beauty of it; but who can tell what that is? Aben Ezra interprets it of the point or centre of the earth.
