New Defender's Study Bible Notes
8:1 a wind. The uniform temperatures of the pre-Flood would have prevented the great atmospheric circulations that now prevail, so that significant wind movements were impossible. With the almost complete precipitation of the waters in the primeval canopy after 150 days, the present latitudinal temperature differentials were soon functioning to initiate tremendous winds all over the earth. These winds, blowing on a shoreless ocean, would certainly generate gigantic surface waves and tidal surges. The latter, superimposed on all the other hydrodynamic and geophysical forces at work, evidently served as the critical factor to trigger great tectonic forces that eventually would restore at least partial equilibrium to the disturbed surface of the earth. The earth’s crust was in a highly unstable condition, with the tremendous subterranean reservoirs now emptied of their pressurized waters and with vast depths of light sediments piling up in the antediluvian sea basins.
8:1 assuaged. As a result of the water subsiding, the phenomena described in Psalm 104:6-9 began to take place. The earth’s crust collapsed deep into the previous subterranean reservoir chambers, forming the present ocean basins, and causing further extrusions of magmas around their peripheries and through openings in their floors. The light sediments in the sea troughs were forced upward by isostatic readjustment to form mountain ranges and plateaus. Thus the waters originally stored in the vapor canopy and the subterranean chambers are now stored mainly in the present ocean basins (these waters would be sufficient to cover a “smoothed” earth to a depth of almost two miles) after the vast topographic adjustments that terminated and followed the Flood.
8:3 continually. This expression, to some degree, suggests a cyclic tidal action, but especially connotes rapid subsidence and drainage. It is significant that all the world’s oceans bear evidence (e.g., sea mounts, submarine canyons, etc.) of former lower levels and that all the world’s continental drainage systems (rivers, lakes) bear evidence of former higher water levels and quantities of flow (e.g., old raised river terraces and lake beaches, vast alluvial valleys and “underfit” streams). These worldwide evidences clearly picture a world in the process of emerging from a recent global inundation.
8:4 seventeenth day of the month. This “resting” of the ark, after its labor of protecting its precious cargo against the terrible cataclysm for five long months, occurred exactly 150 days after the Flood began. It may be significant that, on the anniversary of this date many years later, Jesus Christ rose from the dead! That is, the seventh month of the civil year used by the Jews (almost certainly the calendar used in the Flood narrative) was later set as the first month of their religious year. The Passover was on the fourteenth day of the first month, and Christ rose three days after the Passover. Thus, He “rested” in Joseph’s tomb and then rose from the dead on the seventeenth day of the seventh month of the civil calendar.
