The appointed day for leaving Shittim has come, and Joshua, determined to lose no time, rises "early in the morning." Nor is it without a purpose that so often in the Old Testament narrative, when men of might commence some great undertaking, we are told that it was early in the morning. In all hot climates work in the open air, if done at all, must be done early in the morning or in the evening. But, besides this, morning is the appropriate time for men of great energy and decision to be astir; and it readily connects itself with the New Testament text--"Not slothful in business, fervent in spirit, serving the Lord." The benefits of an early start for all kinds of successful work are in the proverbs of all nations; and we may add that few have reached a high position in the Christian life who could not say, in the spirit of the hymn, "early in the morning my song shall rise to thee." Nor can it easily be understood how under other conditions the precept could be fulfilled--"Whatsoever thy hand findeth to do, do it with thy might."
From Shittim to the banks of the Jordan is an easy journey of a few miles, the road being all over level ground, so that the march was probably finished before the sun had risen high. However strong their faith, it could not be without a certain tremor of heart that the people would behold the swollen river, and mark the walls and towers of Jericho a few miles beyond. Three days are to be allowed, if not for physical, certainly for moral and spiritual preparation for the crossing of the river. The three days are probably the same as those adverted to before (chap. i. 3), just as the order to select twelve men to set up twelve stones (chap. iii. 12) is probably the same as that more fully detailed in chap. iv. 2. The host is assembled in orderly array on the east bank of the Jordan, when the officers pass through to give instructions as to their further procedure. Three such instructions are given.
First, they are to follow the ark. Whenever they see the priests that bear it in motion, they are to move from their places and follow it. There was no longer the pillar of fire to guide them--that was a wilderness-symbol of God's presence, now superseded by a more permanent symbol--the ark. Both symbols represented the same great truth--the gracious presence and guidance of God, and both called the people to the same duty and privilege, and to the same assurance of absolute safety so long as they followed the Lord. Familiar sights are apt to lose their significance, and the people must have become so familiar with the wilderness-pillar that they would hardly think what it meant. Now a different symbol is brought forward. The ark carried in solemn procession by the priests is now the appointed token of God's guidance, and therefore the object to be unhesitatingly followed. A blessed truth for all time was clearly shadowed forth. Follow God implicitly and unhesitatingly in every time of danger, and you are safe. Set aside the counsels of casuistry, of fear, and of worldly wisdom; find out God's will and follow it through good report and through evil report, and you will be right. It was thus that Joshua and Caleb did, and counselled the people to do, when they came back from exploring the land; and now these two were reaping the benefit; while the generation, that would have been comfortably settled in the land if they had done the same, had perished in the wilderness on account of their unbelief.
Secondly, a span of two thousand cubits was to be left between the people and the ark. Some have thought that this was designed as a token of reverence; but this is not the reason assigned. Had it been designed as a token of reverence, it would have been prescribed long before, as soon as the ark was constructed, and began to be carried with the host through the wilderness. The intention was, "that ye may know the way by which you must go" (ver. 4). If this arrangement had not been made, the course of the ark through the flat plains of the Jordan would not have been visible to the mass of the host, but only to those in the immediate neighbourhood, and the people would have been liable to straggle and fall into confusion, if not to diverge altogether. In all cases, when we are looking out for Divine guidance, it is of supreme importance that there be nothing in the way to obscure the object or to distort our vision. Alas, how often is this direction disregarded! How often do we allow our prejudices, or our wishes, or our worldly interests to come between us and the Divine direction we profess to desire! At some turn of our life we feel that we ought not to take a decisive step without asking guidance from above. But our own wishes bear strongly in a particular direction, and we are only too prone to conclude that God is in favour of our plan. We do not act honestly; we lay stress on all that is in favour of what we like; we think little of considerations of the opposite kind. And when we announce our decision, if the matter concern others, we are at pains to tell them that we have made it matter of prayer. But why make it matter of prayer if we do so with prejudiced minds? It is only when our eye is single that the whole body is full of light. This clear space of two thousand cubits between the people and the ark deserves to be remembered. Let us have a like clear space morally between us and God when we go to ask His counsel, lest peradventure we not only mistake His directions, but bring disaster on ourselves and dishonour on His name.
