John Wesley on Numbers 13:22

By the south - Moses having described their progress from south to north, more particularly relates some memorable places and passages. They came - Heb. He came, namely, Caleb, as appears from Jos 14:9,12,14. For the spies distributed their work among them, and went either severally, or by pairs; and it seems the survey of this part was left to Caleb. Anak - A famous giant, whole children these are called, either more generally, as all giants sometimes were, or rather more specially because Arbah, from whom Hebron was called Kiriath - arbah, was the father of Anak, Jos 15:13. And this circumstance is mentioned as an evidence of the goodness of that land, because the giants chose it for their habitation. Before Zoan - This seems to be noted to confront the Egyptians, who vainly boasted of the antiquity of their city Zoan above all places.
