Matthew 23:23
"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].
Luke 11:42
"But it is too bad for you Pharisees! For you give a tenth of your mint, rue and every [other] herb [Note: These were small garden plants used for seasoning or medicine] and [yet] neglect [demonstrating] justice and the love of God [toward others]. But you should have done these things and not neglected to do the other things [as well].
Luke 18:12
I fast [i.e., going without food and/or drink for religious reasons] twice a week and I give [to God's work] a tenth of everything I get.'
Hebrews 7:5-9
For indeed, the descendants of Levi, who are appointed to the priesthood, are commanded by the law of Moses to collect a tenth [of the income] of the Israelites, who are their brothers, even though these brothers are [also] descendants of Abraham.
