Reading the General and the Particular in the Law of the Passover

"And the LORD said unto Moses and Aaron, This is the statute of the Passover" (Exodus 12:43-45). There is a passage that states a general rule at the beginning and a particular at the end, and a particular at the beginning and a general rule at the end. "And you shall be unto Me a kingdom of priests and a holy nation" (Exodus 19:6) is a general rule; "These are the words which you shall speak unto the children of Israel" (ibid.) is a particular. "This is the statute of the Torah" is a general rule; "that they bring you a red heifer" is a particular. "This is the statute of the Passover" is a general rule; "No foreigner shall eat of it" is a particular. [When a verse states] a particular and then a general rule and then a particular again, you include in the general rule only what is like the particular.
