The "names" of YHWH (HaShem, G-d) in the TaNaKh are not "names" but are characteristics of HaShem. The TaNaKh is composed of The Torah ("Teaching", also known as the Five Books of Moses), Nevi'im ("Prophets") and Ketuvim ("Writings")—hence TaNaKh]. Praised be His glorious Name forever and ever.
Paul loved the Torah. If the law was done away with, then we don't have to honor our parents, we can be adulterers and murderers, we can worship other gods, and more! Think about it. Do not be deceived by the doctrines of men. Believe God and keep His commandments.
