Leviticus 24:8

From the children of Israel — And these cakes are said to be received from or offered by the children of Israel, bought with the money which they contributed. By an everlasting covenant — By virtue of that compact made between me and them, by which they were obliged to keep this amongst other commands, and, they so doing, I am obliged to be their God and to bless them. And this may be here called an everlasting covenant, not only because it was to endure as long as the Jewish polity stood, but also because this was to stand everlastingly, or continually, and therefore the new cakes were first brought before the old were taken away.
