Joshua had, for forty years in the wilderness, as minister to Moses, been familiar with the personal presence, the agency, the miraculous power, and the voice of the Messenger, in the tabernacle, in the pillar of cloud by day and of fire by night, on mount Sinai, and on many peculiar and special occasions. His name properly signifies _Saviour_. The Hebrew word Jehoshua is equivalent to the Greek name Jesus, or Saviour. On the occurrence of the war with Amalek, shortly after the passage of the Red Sea, Joshua was appointed by Moses to command the army of the Israelites. He led out the chosen men of war, while Moses, Aaron, and Hur took their station on a neighboring hill, where Moses held up the rod of God, as a token that all the success under Joshua, in the destruction of the Amalekites, was owing to the superior power of Jehovah exerted specially on the occasion. When Moses held up his hand, Israel prevailed; and when he let down his hand, Amalek prevailed. The battle being ended by the discomfiture of Amalek and his people, Jehovah said unto Moses, "Write this for a memorial, and rehearse it in the ears of Joshua, That I will utterly put out the remembrance of Amalek from under heaven. And Moses built an altar, and called the name of it Jehovah Nissi," _i. e._, the Lord my banner. Exod. xvii. Thus the supremacy and leadership of Jehovah was fully acknowledged. It was his war, executed under the lieutenancy of Joshua, in accordance with the specific directions given to Moses, and in the exercise of faith in the will of Jehovah, as indicated by tokens of his appointment. On the occasion of the giving of the tables of stone, Joshua accompanied Moses, as his minister, into the mount of God. There they tarried forty days, while "the sight of the glory of Jehovah was like devouring fire on the top of the mount, in the eyes of the children of Israel." The directions concerning the construction of the tabernacle were given on that occasion. Exod. xxiv. When they descended from the mount, Joshua seems first to have heard the shouting of the people before the molten image they had made. Exod. xxxii. In the progress of the events which succeeded this defection, the cloudy pillar--the Shekina--descended from Sinai, and stood at the door of the tabernacle, and Jehovah talked with Moses. "And Jehovah spake unto Moses face to face, as a man speaketh unto his friend. And Moses turned again into the camp, but his minister Joshua departed not out of the tabernacle." He, therefore, doubtless heard and saw the same as Moses. Ibid. xxxiii. He was one of those sent to examine and report concerning the land of Canaan, Numb. xiii.; on which occasion, Moses changed his name from Oshea to Jehoshua. Ten of those sent were unfaithful. The joint report of Joshua and Caleb was true and faithful. The ten were destroyed by a plague; the two were protected and preserved. Ibid. xiv.
