I'm not sure if this is to do with Hebrew being translated to Greek, but when looking at "The greatest commandment" Deuteronomy 6:5 says:

> 
> "And thou shalt love the LORD thy God with all thy heart, and with all thy soul, and with all thy might." (KJV)
> 
> 
> 

Jesus seems to quote the same verse in the New Testament:

* Matthew 22:37 quoting the same verse has the words *heart, soul* and *mind* (KJV).
* Mark 12:30 quoting the same verse has the words *heart, soul, mind* and *strength* (KJV).
* Luke 10:27 quoting the same verse has the words *heart, soul, strength* and *mind* (KJV).

Why is the word "mind" quoted by Jesus in the New Testament, but not in Dueteronomy 6:5 when I read the Old Testament? Did Jesus add to what Moses said originally?
