Joshua 4:14

On that day the Lord magnified Joshua. This was not, as Calvin remarks, the chief aim of the miracle. But it was, nevertheless, one important result of it. Joshua was the appointed leader of the Israelites, and he was under God's special protection and guidance. But however much God may overrule our human nature to His own purposes, He never abrogates the laws of its working. Confidence in a leader, from a human point of view, is one of the most essential requisites for success in war. Therefore in the crossing of the Jordan we find Joshua directing all the operations, though the direction of affairs might have been put into other hands, that of Eleazar the high priest, for instance. But this was the public attestation of the secret intimation God had given Joshua ( Joshua 1:5 ): "As I was with Moses, so will I be with thee: I will not fail thee nor forsake thee." From this point onward we see no signs of hesitation on the part of the Israelites; nothing but the most unwavering confidence in the Divine mission, as well as in the extraordinary natural gifts, of their leader.
