None shall be weary nor stumble among them; none shall slumber nor sleep; neither shall the girdle of their loins be loosed, nor the latchet of their shoes be broken:
None shall be weary - with long marches (Deuteronomy 25:18).
None shall slumber - requiring little or no rest: so energetic shall they be in their invasion.
Neither shall the girdle of their loins be loosed - with which the ancient loose robes used to be girded for action: ever ready for march or battle.
Nor the latchet of their shoes be broken. The soles were attached to the feet, not by upper leather, as with us, but by straps. So securely clad that not even a strap of their sandals gives way, so as to impede their march.
