'Reach' in the Bible

Therefore, let everyone who is godly pray to You [for forgiveness] in a time when You [are near and] may be found;Surely when the great waters [of trial and distressing times] overflow they will not reach [the spirit in] him.

For Your lovingkindness is great and higher than the heavens;Your truth reaches to the skies.

Such [infinite] knowledge is too wonderful for me;It is too high [above me], I cannot reach it.
