John Calvin

“ For we know, that in order to sacrifice duly, it was enjoined that all should have one common altar, in order both to cherish mutual agreement, and to obviate all sources of corruption from the introduction of an adventitious superstition; in short, in order that religion might remain one and simple, as a variety of altars would soon have led to discord, thereby distracting the people and putting sincere piety to flight. ”

“ The intervening space was occupied by the Levites with the ark of the covenant, that the Lord might be surrounded on all sides by his own people. It is said that Joshua stood that he might first bless the people, as it was the purpose of God to allure the people to himself by sweetness and winning condescension. For although Moses, to rebuke the obstinacy of the people, makes mention of curses only, it is certain that these were in a manner accidental, because the genuine method was to employ blessings as a means of gaining over to obedience those who might otherwise have proved refractory. ”

“ Some expounders, in searching for the reason, needlessly have recourse to allegory, and allege that the hand and industry of men are forbidden, because the moment we introduce any devices of our own, the worship of God is vitiated. ”
