Barnes' Notes
Who hath laid the measures thereof - That is, as an architect applies his measures when he rears a house.
If thou knowest - Or rather, "for thou knowest." The expression is wholly ironical, and is designed to rebuke Job' s pretensions of being able to explain the divine administration.
Or who hath stretched the line upon it - As a carpenter uses a line to mark out his work; see the notes at Isaiah 28:17. The earth is represented as a building, the plan of which was laid out beforehand, and which was then made according to the sketch of the architect. It is not, therefore, the work of chance or fate. It is laid out and constructed according to a wise plan, and in a method evincing infinite skill.
