You shall compass the city, all the men of war, going about the city once. Thus shall you do six days.
And the details of the orders given by God to Joshua Joshua 6:3-5 illustrate this last point further. The trumpets employed were not the silver trumpets used for signalling the marshalling of the host and for other warlike purposes (compare Numbers 10:2), but the curved horns employed for ushering in the Jubilee and the Sabbatical Year (Septuagint, σάλπιγγες ἱεραί salpinges hierai: compare the Leviticus 23:24 note). The trumpets were borne by priests, and were seven in number; the processions round Jericho were to be made on seven days, and seven times on the seventh day, thus laying a stress on the sacred number seven, which was an emhlem more especially of the work of God. The ark of God also, the seat of His special presence, was carried round the city. All these particulars were calculated to set forth symbolically, and in a mode sure to arrest the attention of the people, the fact that their triumph was wholly due to the might of the Lord, and to that covenant which made their cause His.
