Jesus is the Name the Godhead has chosen to represent them.
For in Him dwells all the fullness of the Godhead bodily;
Colossians 2:9
Jesus is YHWH; The LORD God. The Creator of heaven and earth.
But to the Son He says:
“Your throne, O God, is forever and ever;
A scepter of righteousness is the scepter of Your kingdom.
You have loved righteousness and hated lawlessness;
Therefore God, Your God, has anointed You
With the oil of gladness more than Your companions.”
And:
“You, LORD, in the beginning laid the foundation of the earth,
And the heavens are the work of Your hands.
Hebrews 2:8-10
Whenever we see the LORD in the Old Testament it refers to Jesus Christ the Son.
