Thematic Bible: Exact in minor, but neglecting important duties

"It is too bad for you hypocritical experts in the law of Moses and [you] Pharisees! 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. You should have done these ["lighter"] things and not neglected to do the other ["heavier"] things [as well]. You blind leaders, who strain out a [tiny] gnat [i.e., from your drinking water] and [yet] swallow a [whole] camel.
