Leviticus 10:10

²⁶Her priests have done violence to my law and have profaned my holy things. They have made no distinction between the holy and the common, neither have they caused men to discern between the unclean and the clean, and have hidden their eyes from my Sabbaths. So I am profaned among them.

¹⁴as children of obedience, not conforming yourselves according to your former lusts as in your ignorance, ¹⁵but just as he who called you is holy, you yourselves also be holy in all of your behavior, ¹⁶because it is written, “You shall be holy, for I am holy.”

⁴⁷to make a distinction between the unclean and the clean, and between the living thing that may be eaten and the living thing that may not be eaten.’”

¹⁵To the pure, all things are pure, but to those who are defiled and unbelieving, nothing is pure; but both their mind and their conscience are defiled.

²³They shall teach my people the difference between the holy and the common, and cause them to discern between the unclean and the clean.

¹⁹Therefore the LORD says, “If you return, then I will bring you again, that you may stand before me; and if you take out the precious from the vile, you will be as my mouth. They will return to you, but you will not return to them.

²⁵“‘You shall therefore make a distinction between the clean animal and the unclean, and between the unclean fowl and the clean. You shall not make yourselves abominable by animal, or by bird, or by anything with which the ground teems, which I have separated from you as unclean for you. ²⁶You shall be holy to me, for I, the LORD, am holy, and have set you apart from the peoples, that you should be mine.
