For you give a tenth of your mint, dill and cumin [i.e., small garden herbs used for seasoning or fragrance], and [yet] neglect the heavier responsibilities required by the law, [such as] justice, mercy and faith.

When he lies, he only speaks what is part of his nature, because he is a liar and the father of [all] liars.
