My servant Caleb - Caleb only is mentioned here as also in Numbers 13:30 ff. Both passages probably form part of the matter introduced at a later period into the narrative of Moses, and either by Joshua or under his superintendence. Hence, the name of Joshua is omitted, and his faithfulness together with its reward are taken for granted. In Numbers 14:30, Numbers 14:38, both names are mentioned together; and these verses in all likelihood belong to the same original composition as Numbers 14:6-10.
