TSK · Leviticus 11:47

and that you are to make a distinction between the holy and the common, and between the unclean and the clean;

Then you shall return and discern between the righteous and the wicked, between him who serves God and him who doesn't serve him.

Therefore let's not judge one another any more, but judge this rather, that no man put a stumbling block in his brother's way, or an occasion for falling.
