15 It happened on the seventh day, that they rose early at the dawning of the day, and marched around the city in the same way seven times. Only on this day they marched around the city seven times. 16 It happened at the seventh time, when the priests blew the trumpets, Joshua said to the people, “Shout, for Yahweh has given you the city!

17 The city shall be devoted, even it and all that is in it, to Yahweh. Only Rahab the prostitute shall live, she and all who are with her in the house, because she hid the messengers that we sent. 18 But as for you, only keep yourselves from the devoted thing, lest when you have devoted it, you take of the devoted thing; so would you make the camp of Israel accursed, and trouble it. 19 But all the silver, and gold, and vessels of brass and iron, are holy to Yahweh. They shall come into Yahweh’s treasury.” 20 So the people shouted, and the priests blew the trumpets. It happened, when the people heard the sound of the trumpet, that the people shouted with a great shout, and the wall fell down flat, so that the people went up into the city, every man straight before him, and they took the city.

Commentary on Joshua 6:6-16

(Read Joshua 6:6-16)

Wherever the ark went, the people attended it. God's ministers, by the trumpet of the everlasting gospel, which proclaims liberty and victory, must encourage the followers of Christ in their spiritual warfare. As promised deliverances must be expected in God's way, so they must be expected in his time. At last the people were to shout: they did so, and the walls fell. This was a shout of faith; they believed the walls of Jericho would fall. It was a shout of prayer; they cry to Heaven for help, and help came.

Commentary on Joshua 6:17-27

(Read Joshua 6:17-27)

Jericho was to be a solemn and awful sacrifice to the justice of God, upon those who had filled up the measure of their sins. So He appoints, from whom, as creatures, they received their lives, and to whom, as sinners, they had forfeited them. Rahab perished not with them that believed not, Acts 14:31. She, and they with her, were plucked as brands from the burning. With Rahab, or with the men of Jericho; our portion must be assigned, as we posses or disregard the sign of salvation; even faith in Christ, which worketh by love. Let us remember what depends upon our choice, and let us choose accordingly. God shows the weight of a Divine curse; where it rests there is no getting from under it; for it brings ruin without remedy.
