'Teach' in the Bible

Its priests treat my law violently, and they profane my holy objects; they do not distinguish between holy object and what is unholy, or between the clean and the unclean. They do not teach the difference, and they hide their eyes from my Sabbaths, and [so] I am profaned in the midst of them.

And they will teach my people [the difference] between what is holy and what is unholy, and [the difference] between unclean and clean they must show them.
