Both are correct.
In most cases, when using the expression, “the LORD” [“Yahweh” in the Hebrew, basically meaning “The Eternal” or “The Everliving One”], the Old Testament refers to the One Who later became known as the Son, Jesus Christ. There are statements, however, which use the expression “Yahweh” for the One Who later became known as “the Father.” This also proves that both the Father and Jesus Christ have always been God beings, and that the Old Testament teaches that there is more than just one God being.
Notice Jeremiah 23:5-6, which uses the term “Yahweh” for both God beings in the same context:
“‘Behold, the days are coming,’ says the LORD [Yahweh], ‘That I will raise to David a Branch of righteousness; A King shall reign and prosper, And execute judgment and righteousness in the earth. In His days Judah will be saved, And Israel will dwell safely; Now this is His name by which He will be called: THE LORD [Yahweh] OUR RIGHTEOUSNESS.'”
