'Wanderers' in the Bible

Your sons shall be wanderers and shepherds in the wilderness for forty years, and they will suffer for your unfaithfulness (spiritual infidelity), until your corpses are consumed in the wilderness.

My God will reject them and cast them awayBecause they did not listen to Him;And they will be wanderers (fugitives) among the nations.

Keep your behavior excellent among the [unsaved] Gentiles [conduct yourself honorably, with graciousness and integrity], so that for whatever reason they may slander you as evildoers, yet by observing your good deeds they may [instead come to] glorify God in the day of visitation [when He looks upon them with mercy].
