Joshua 3:7 And the Lord said unto Joshua, This day will I begin to magnify thee in the sight of all Israel, that they may know that, as I was with Moses, so I will be with thee. 8 And thou shalt command the priests that bear the ark of the covenant, saying, When ye are come to the brink of the water of Jordan, ye shall stand still in Jordan.
[Patriarchs & Prophets pp 483>484] Leaving their encampment in the acacia groves of Shittim, the host descended to the border of the Jordan. All knew, however, that without divine aid they could not hope to make the passage. At this time of the year—in the spring season—the melting snows of the mountains had so raised the Jordan that the river overflowed its banks, making it impossible to cross at the usual fording places. God willed that the passage of Israel over Jordan should be miraculous. Joshua, by divine direction, commanded the people to sanctify themselves; they must put away their sins and free themselves from all outward impurity; “for tomorrow,” he said, “the Lord will do wonders among you.”
The “ark of the covenant” was to lead the way before the host. When they should see the token of Jehovah's presence, borne by the priests, remove from its place in the center of the camp, and advance toward the river, then they were to remove from their place, “and go after it.” The circumstances of the passage were minutely foretold; and said Joshua, “Hereby ye shall know that the living God is among you, and that He will without fail drive out from before you the Canaanites.... Behold, the ark of the covenant of the Lord of all the earth passeth over before you into Jordan.”
At the appointed time began the onward movement, the ark, borne upon the shoulders of the priests, leading the van. The people had been directed to fall back, so that there was a vacant space of more than half a mile about the ark. All watched with deep interest as the priests advanced down the bank of the Jordan. They saw them with the sacred ark move steadily forward toward the angry, surging stream, till the feet of the bearers were dipped into the waters. Then suddenly the tide above was swept back, while the current below flowed on, and the bed of the river was laid bare.
Joshua 3:12 Now therefore take you twelve men out of the tribes of Israel, out of every tribe a man. 13 And it shall come to pass, as soon as the soles of the feet of the priests that bear the ark of the Lord, the Lord of all the earth, shall rest in the waters of Jordan, that the waters of Jordan shall be cut off from the waters that come down from above; and they shall stand upon an heap.
May The Lord add His blessing to the study of His word. God bless!
