The LORD is One

Deuteronomy 6:4 contains the famous Hebrew prayer known as the Shema.
In English, it reads:
“Hear, O Israel: The LORD our God, the LORD is one!

The word Echad is the word translated as “one”
This is the profound declaration of Biblical monotheism. But the word “echad” has some very special meaning for us to discover.
The word “echad” is used in Scripture to describe something of many parts that come together to form one complete unit.
We see this in Genesis 2:24 when God creates the man and the woman and it is declared:
Therefore, a man shall leave his father and mother and be joined to his wife,
and they shall become one flesh. Genesis 2:24
This verse speaks of two separate people coming together to be ONE flesh
In the Shema, God reveals something very special about His nature. From the rest of Scripture, we know the three persons of this Divine Unity to be the Father, the Son and the Holy Spirit.
Behold – The Lord your God, The Lord is one.
