New Defender's Study Bible Notes
8:27 compass. “Compass” (Hebrew khug) is the same word as “circle” in Isaiah 40:22, as well as “compassed” in Job 26:10. All three clearly refer to the roundness of the earth, especially to the spherical nature of sea level, defining, as it were, the global shape of the earth. The Bible never teaches a flat earth, though the charge is frequently made.
8:27 depth. “Depth” is the same word as “deep.”
