The Law of Moses commanded that a tithe, or ten percent of all goods, produce, flocks and cattle, be given to the Lord to sustain the Priests, Levites and the poor (see Leviticus 27:30-33, Numbers 18:21-28) . The Pharisees, however, in their desire to be overly zealous in their obedience, seemed to take this law to an extreme by paying a tithe on even the smallest of personal belongings, that of spices.
|The spices mint, dill, and cumin as mentioned by Jesus|
To further teach his point of focusing on the minute level of obedience, Jesus criticizes the Pharisees for their act of straining out gnats and other insects from their wine before drinking, while symbolically eating a camel instead . The Law of Moses prescribed that most insects (besides locust, grasshoppers and crickets) were considered unclean, along with many other animals including pigs, lizards, frogs, and camels, to only name a few .

How do we obey the Laws of God? Do we see them just a long list of checkboxes and dos and don’ts? Do we only obey the commandments that others will see? Or do we seek to understand the true purpose of the law by looking to better understand how the law draws us towards God, and towards serving, helping, and loving others.
