When he gave to the sea his decree, that the waters should not pass his commandment: when he appointed the foundations of the earth:
When he gave to the sea his decree, that the waters should not pass his commandment - (Job 38:10-11; Psalms 104:9; Jeremiah 5:22.) "Commandment" - literally, 'His mouth,' (cf. Numbers 3:16, margin) Maurer takes it 'the mouth,' or 'shore of the sea.'
When he appointed the foundations of the earth - when He made it as stable as a building resting on solid foundations. The earth's center is its virtual foundation, as all bodies and parts of the earth, by the centripetal force of attraction, gravitate toward it. Job 26:7 hints at the true theory of the earth's foundation.
