"For six days the host of Israel performed their circuit around the city. The seventh day came, and, with the first dawn of light, Joshua marshaled the armies of the Lord. Now they were directed to march seven times around Jericho, and, at a mighty note of the trumpets, to shout with a loud voice, for God had then given them the city. The imposing army marched solemnly around the devoted walls. The resplendent ark of God lighting the early dusk of morning, the priests with their glittering breastplates and jeweled badges, and the warriors with their flashing armor presented a magnificent pageant. They were silent as the dead, save the measured tread of many feet and the occasional blare of the trumpet, cutting the blank stillness of the early morning. The massive walls of solid stone frowned darkly down, defying the siege of men. 4T 161.1"
"And the second day they compassed the city once, and returned into the camp: so they did six days."
The EGW passage directly recounts the events of Joshua 6:14, describing the marching around Jericho for six days.
"Suddenly the vast army halts. The trumpets break forth in a blast that shakes the very earth. The united voices of all Israel rend the air with a mighty shout. The walls of solid stone, with their massive towers and battlements, totter and heave from their foundations and, with a crash like a thousand thunders, fall in shapeless ruin to the earth. The inhabitants and the army of the enemy, paralyzed with terror and amazement, offer no resistance, and Israel marches in and takes captive the mighty city of Jericho. 4T 161.2"
"So the people shouted when the priests blew with the trumpets: and it came to pass, when the people heard the sound of the trumpet, and the people shouted with a great shout, that the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city."
The EGW passage is a clear retelling of the events in Joshua 6:20, specifically the trumpets, shouting, and the walls falling.
