5 Who determined its measurements? Surely you know! Or who stretched the line upon it?

Matthew Henry's Commentary on Job 38:5

Commentary on Job 38:4-11

(Read Job 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.
