Joshua 6:4 YLT

²  And Jehovah saith unto Joshua, 'See, I have given into thy hand Jericho and its king -- mighty ones of valour,

³  and ye have compassed the city -- all the men of battle -- going round the city once; thus thou dost six days;

⁴  and seven priests do bear seven trumpets of the jubilee before the ark, and on the seventh day ye compass the city seven times, and the priests blow with the trumpets,

⁵  and it hath been, in the prolongation of the horn of the jubilee, in your hearing the voice of the trumpet, all the people shout -- a great shout, and the wall of the city hath fallen under it, and the people have gone up, each over-against him.'

⁶  And Joshua son of Nun calleth unto the priests, and saith unto them, 'Bear ye the ark of the covenant, and seven priests do bear seven trumpets of the jubilee before the ark of Jehovah;'
