Deuteronomy 12:8

Here; where the inconveniency of the place, and the uncertainty of our abode in and removal from several places, would not permit exact order in sacrifices, and feasts, and ceremonies, which therefore God was pleased then to dispense with; but, saith he, he will not do so there. Every man whatsoever is right in his own eyes; not that universal liberty was given to all persons to worship whom and how they listed, but that in many things their unsettled condition gave every one opportunity to do so if he thought good.
