the LORD thy God led thee these forty years in the wilderness, to humble
thee, [and] to prove thee, to know what [was] in thine heart, whether thou
wouldest keep his commandments, or no.
BSB
Remember that these forty years the LORD your God led you all the way in the wilderness, so that He might humble you and test you in order to know what was in your heart, whether or not you would keep His commandments.
