Job 9:8

The point lies in the gigantic power of God who "alone" and of Himself stretched out the heavens; cf. the expression of the same idea of power, Isaiah 40:12; Isaiah 44:24. In Isaiah 40:22 it is said that God stretches out the heavens as a curtain and spreadeth them out as a tent to dwell in. Our "firmament" is a relic of a false astronomy for which scripture is not responsible.

waves of the sea lit. heightsof the sea, cf. heights of the earth, Amos 4:13. The "sea" here is scarcely the celestial waters, Psalms 29:3. God is represented as walking on the sea when its waves mount up to heaven, and His voice may be heard in the thunder.
