The ironical words of one that seems to be in a great rage: Take those that are peculiar, and to be all burnt to me, Leviticus 1:9, and put them to your own of what kind soever; eat them, and do what you will with them, I will have none of them; take it all and fill your own bellies, for you sacrifice not to me, but to yourselves. See Hosea 9:4, where their meat-offerings are called in scorn meat for their life to nourish their bodies. Unto your sacrifices; that part of your sacrifices which you are allowed to eat; they are but as profane food; do not you think to be sanctified by them, because I accept them not.
