Joshua 4:1 - Joseph Benson’s Commentary on the Old and New Testaments

The Lord spake unto Joshua This was commanded before, (Joshua 3:12,) and is here repeated with enlargement, as being now to be put in execution. It is the pious conjecture of the learned Bishop Patrick, that Joshua was gone into some place of retirement, to return thanks immediately for this wonderful mercy; and then God met him and spake thus to him. Or, perhaps, it was by Eleazar the priest that God gave these and other instructions to Joshua; for though he is not mentioned here, yet, when Joshua was ordained by the imposition of hands to this great trust, God appointed that Eleazar should ask counsel for him, after the judgment of Urim; and at his word Joshua and all the children of Israel were to go out and come in, Numbers 27:21.
