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?
On whatever grounds Joshua was appointed, the result amply vindicated the selection. On Joshua's part there is none of that hesitation in accepting his work which was shown even by Moses himself when he got his commission at the burning bush. He seems to have accepted the appointment with humble faith and spirited enthusiasm, and prepared at once for the perilous enterprise.
And he had little enough time to prepare, for a new attack of the Amalekites was to be made next day. We may conceive him, after prayer to his Lord, setting out with a few chosen comrades to invite volunteers to join his corps, rousing their enthusiasm by picturing the dastardly attack that the Amalekites had made on the sick and infirm (Deut. xxv. 17, 18), and scattering their fears by recalling the promise to Abraham, "I will bless them that bless thee, and curse him that curseth thee." That Moses knew him to be a man of faith whose trust was in the living God was shown by his promise to stand next morning on the hill top with the rod of God in his hand. Yes, the rod of God! Had not Joshua seen it stretched out over the Red Sea, first to make a passage for Israel, and thereafter to bring back the waters on Pharaoh's host? Was he not just the man to value aright that symbol of Divine power? The troop selected by Joshua may have been small as the band of Gideon, but if it was as full of faith and courage it was abundantly able for its work!
The Amalekites are sometimes supposed to have been descendants of an Amalek who was the grandson of Esau (Gen. xxxvi. 12), but the name is much older (Gen. xiv. 7), and was applied at an early period to the inhabitants of the tract of country stretching southwards from the Dead Sea to the peninsula of Sinai. Whatever may have been their origin, they were old inhabitants of the wilderness, well acquainted probably with every mountain and valley, and well skilled in that Bedouin style of warfare which even practised troops are little able to meet. They were therefore very formidable opponents to the raw levy of Israelites, who could be but little acquainted with weapons of war, and were wholly unaccustomed to battle.
The Amalekites could not have been ignorant of the advantage of a good position, and they probably occupied a post not easy to attack and carry. Evidently the battle was a serious one. The practised and skilful tactics of the Amalekites were more than a match for the youthful valour of Joshua and his comrades; but as often as the uplifted rod of Moses was seen on the top of the neighbouring hill, new life and courage rushed into the souls of the Israelites, and for the time the Amalekites retreated before them. Hour after hour the battle raged, till the arm of Moses became too weary to hold up the rod. A stone had to be found for him to sit on, and his comrades, Aaron and Hur, had to hold up his hands. But even then, though the advantage was on the side of Joshua, it was sunset before Amalek was thoroughly defeated. The issue of the battle was no longer doubtful – "Joshua discomfited Amalek and his people with the edge of the sword" (Exod. xvii. 13).
It was a memorable victory, due in effect to the hand of God as really as the destruction of the Egyptians had been, but due instrumentally to the faith and fortitude of Joshua and his troop, whose ardour could not be quenched by the ever-resumed onslaughts of Amalek. And when the fight was over, Joshua could not but be the hero of the camp and the nation, as really as David after the combat with Goliath. Congratulations must have poured on him from every quarter, and not only on him, but on his father and grandfather as well. To Joshua these would come with mingled feelings; gratification at having been able to do such a service for his people, and gratitude for the presence of Him by whom alone he had prevailed. "Not unto us, Lord, not unto us, but to Thy name be the glory." It was a splendid beginning for Israel's wilderness history, if only it had been followed up by the people in a kindred spirit. But there were not many Joshuas in the camp, and the spirit did not spread.
It is remarkable what a hold that incident at Rephidim has taken on the Christian imagination. Age after age, for more than three thousand years, its influence has been felt. Nor can it ever cease to impress believing men that, so long as Moses holds out his rod, so long as active trust is placed in the power and presence of the Most High in the great battle with sin and evil, Israel must prevail; but if this trust should fail, if Moses should let down his rod, Amalek will conquer. It was well that Moses was instructed to write the transaction in a book and rehearse it before Joshua. Well also that it should be commemorated by another memorial, an altar to the Lord with the name of "Jehovah-nissi," the Lord my banner. How often has faith looked out towards that unknown mountain where Aaron and Hur held up the weary arms of Moses, and what a new thrill of courage and hope has the spectacle sent through hearts often "faint yet pursuing"! Happily on Joshua the effect was wholesome; a less spiritual man would have been puffed up by his remarkable victory; but in him its only effect, as was shown by the whole tenor of his future life, was a firmer trust in God, and a deeper determination to wait only on Him.
It was no wonder that after this Joshua was selected by Moses to be his personal comrade and attendant in connection with that most solemn of all his duties – the receiving of the law on the top of the mount. Here again was a most distinguished honour for so young a man. Aaron, Nadab, and Abihu, with seventy of the elders, were summoned to ascend to a certain height and worship afar off; while Moses, accompanied by Joshua, went up into the mount of God (Exod. xxiv. 13). What became of Joshua while Moses was in immediate fellowship with God is not very apparent. The first impression we derive from the narrative is that he was with Moses all the time, for when Moses begins his descent Joshua is at his side (Exod. xxxii. 17). Yet we cannot suppose that in that most solemn transaction of Moses with Jehovah when the law was given any third party was present. On a careful study of the narrative throughout it will probably be seen that when, after going up a certain distance in company with Aaron and his sons and the seventy elders, Moses was called to a higher part of the mount, Joshua accompanied Moses (Exod. xxiv. 13), and that he was with Moses during the six days when the glory of God abode on Mount Sinai and a cloud covered the mount (ver. 15); but that when God again, after these six days, called to Moses to ascend still higher, and Moses "went into the midst of the cloud, and gat him up to the mount" (ver. 18), Joshua remained behind. His place of rest would thus be half-way between the spot where the elders saw God's glory and the summit where God talked with Moses. But the remarkable thing is, that from that place Joshua would seem never to have moved all the forty days and forty nights when Moses was with God. We can hardly conceive a case of more remarkable obedience, a more striking instance of the quiet waiting of faith. To a youth of his spirit and habits
