Numbers 14:33

Shall wander in the wilderness Hebrew, יהיו רעים, Jehju rognim, shall feed, shall seek their food from place to place, after the manner of the Arabian shepherds, that were forced to remove their tents from one place to another, that they might find pasture for their flocks. Forty years Reckoning from the time of their first coming out of Egypt into the wilderness, where they had already wandered a year and a half. And bear your whoredoms The punishment of your whoredoms, that is, of your idolatries, of your apostacy from, and perfidiousness against the Lord, who was your husband, having espoused you to himself by covenant. Idolatry and apostacy from God's worship are continually represented under the idea of whoredom in the Scripture. And it appears from Amos 5:25, that the Israelites were every now and then falling off to this sin during the whole period of these forty years in the wilderness.
