WHAT DOES SHEMA MEAN?
In the simplest terms, shema means, “hear and obey” as was recorded in Mark 12:29 and Deuteronomy 6:4.

One of the scribes came and heard them arguing, and recognizing that He had answered them well, asked Him, “What commandment is the foremost of all?” Jesus answered, “The foremost is, ‘Hear, O Israel! The Lord our God is one Lord; and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength. ’ The second is this, ‘ You shall love your neighbor as yourself. ’ There is no other commandment greater than these.  Mark 12:28-31 NASB

Directly quoting Deuteronomy 6:4-5 and Leviticus 19:18, Yeshua (Jesus) commanded His followers (Israel) to Hear, Listen to and Obey the commands, “The Lord our God is one Lord; and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.”  If we truly love Yeshua, our love is shown by keeping His commandments (1 Jn 5:2 & 3, 2 Jn 1:6, Jn 14:15 & 21).  When He said, "Hear," (Shema), He was telling His followers to listen to and obey His and the Father's commandments, which are the same.  In John 14:8-11 He said that He and the Father are one.  If you have seen Him, you have seen the Father.  According to the TWOT, Shema, שָמַע (shāmaa) means to “hear, listen to, obey” and is Strong’s h8085.  Below is a great 3 1/2 minute teaching from "The Bible Project" on this Hebrew word called "Shema.":
