Deuteronomy 32:35

Their feet shall slide — They who now think they stand fast and unmoveable, shall fall into utter destruction. In due time — Though not so soon as some may expect, yet in that time when it shall be most proper, when they have filled up the measure of their sins. At hand — Heb. is near. So the scripture often speaks of those things which are at many hundred years distance, to signify, that though they may be afar off as to our measures of time, yet in God's account they are near, they are as near as may be, when the measure of their sins is once full, the judgment shall not be deferred.
