Four hundred years is a long way to go back in tracing a pedigree. Joshua's might have been traced much farther back than that--back to Noah, or for that matter to Adam; but Israelites usually counted it enough to begin with that son of Jacob who was the head of their tribe. It could be no small gratification to Joshua that he had Joseph for his ancestor, and that of the two sons of Joseph he was sprung from the one whom the dying Jacob so expressly placed before the other as the heir of the richer blessing (1 Chron. vii. 20-27). It is remarkable that the descendants of Joseph attached no consequence to the fact that on the side of Joseph's wife they were sprung from one of the highest functionaries of Egypt (Gen. xli. 45), any more than the children of Mered, of the tribe of Judah, whose wife, Bithiah, was a daughter of Pharaoh (1 Chron. iv. 18), gained rank in Israel from the royal blood of their mother. The glory of high connections with the heathen counted for nothing; it was entirely eclipsed by the glory of the chosen seed. To be of the household of God was higher than to be born of kings.
Joshua appears to have come of the principal family of the tribe, for his grandfather, Elishama (1 Chron. vii. 26), was captain and head of his tribe (Num. i. 10, ii. 18), and in the order of march through the wilderness marched at the head of the forty thousand five hundred men that constituted the great tribe of Ephraim; while his son, Nun, and his grandson, Joshua, would of course march beside him. Not only was Elishama at the head of the tribe, but apparently also of the whole "camp of Ephraim," which, besides his own tribe, embraced Manasseh and Benjamin, being the whole descendants of Rachel (Num. ii. 24). Under their charge in all likelihood was a remarkable relic that had been brought very carefully from Egypt--the bones of Joseph (Exod. xiii. 19). Great must have been the respect paid to the coffin which contained the embalmed body of the Governor of Egypt, and which was never lost sight of during all the period of the wanderings, till at length it was solemnly deposited in its resting-place at Shechem (Josh. xxiv. 32). Young Joshua, grandson of the prince of the tribe, must have known it well. For Joshua was himself cast in the mould of Joseph, an ardent, courageous, God-fearing, patriotic youth. Very interesting to him it must have been to recall the romance of Joseph's life, his grievous wrongs and trials, his gentle spirit under them all, his patient and invincible faith, his lofty purity and self-control, his intense devotion to duty, and finally his marvellous exaltation and blessed experience as the saviour of his brethren! And that coffin must have seemed to Joshua ever to preach this sermon,--"God will surely visit you." With Joseph, young Joshua believed profoundly in his nation, because he believed profoundly in his nation's God; he felt that no other people in the world could have such a destiny, or could be so worthy of the service of his life.
This sense of Israel's relation to God raised in him an enthusiastic patriotism, and soon brought him under the notice of Moses, who quickly discerned in the grandson a spirit more congenial to his own than that of either the father or the grandfather. Not even Moses himself had a warmer love than Joshua for Israel, or a more ardent desire to serve the people that had such a blessed destiny. In all likelihood the first impression Joshua made on Moses might have been described in the words--"It came to pass that the soul of Moses was knit with the soul of Joshua, and Moses loved him as his own soul."
In no other way can we account for the extraordinary mark of confidence with which Joshua was honoured when he was selected in the early days of the wilderness sojourn, not only to repel the attack which the Amalekites had made upon Israel, but to choose the men by whom this was to be done. Why pass over father and grandfather, if this youth, Joshua, had not already displayed qualities that fitted him for this difficult task better than either of them? We cannot but note, in passing, the proof we have of the contemporaneousness of the history, that no mention is made of the reasons why Joshua of all men was appointed to this command. If the history was written near the time, with Joshua's splendid career fresh in the minds of the people, the reasons would be notorious and did not need to be given; if it was written long afterwards, what more natural than that something should be said to explain the remarkable choice?
