Does Judges 13 Mention the Trinity?

And an angel of the Lord appeared to the woman, and said to her, "Behold now, you are barren, and have not borne; and you shall conceive and bear a son. (Judges 13:1)

Some Christians claim that this angel was as well an incarnation of God according to the following verse:

And Manoah said to his wife, "We shall surely die, because we have seen God." (Judges 13:22)

However, this overlooks two major points. The first point is the one that we have been discussing until now, which is that the Torah often refers to visions of angels as visions of God. The second point is explicitly in all of the verses in this chapter preceding verse 22 (the phrase "an angel of God" appears ten times), all of which repeatedly refer to this being as "an angel of God." In addition, several of these verses explicitly distinguish between God and the angel:

And God hearkened to the voice of Manoah; and the angel of God came again to the woman, and she was sitting in the field, and Manoah her husband was not with her. (Genesis 13:9)

And Manoah said to the angel of the Lord, "Let us take you in now, and prepare for you a kid goat." And the angel of the Lord said to Manoah, "If you take me in I will not eat of your bread, and if you will make a burnt-offering, you must offer it to the Lord;" For Manoah did not know that he was an angel of the Lord. (Genesis 13:15-16)

Some Christians argue, however, that Manoach and his wife only thought that it was an angel, but it was really God. Further, the only reason that the angel continues to accept being referred to as the angel of God is to avoid causing Manoach and his wife to mistakenly commit "idolatry in their hearts" by offering a sacrifice to an angel, which is the reason that it tells them to offer the sacrifice to God.

However, there are two issues with this as well. Manoach did not say that he intended to offer the goat to the angel as a sacrifice, but rather believing that it was a human being, like Abraham he offered to prepare food for him. Secondly, if the angel was really God, and God sought to reveal Himself as a Trinity, it would have simply said, "No, I am God in the form of an angel, so you may prepare the sacrifice to Me." For some odd reason God chose to keep his true Nature as a Trinity hidden, which is why I say that the apparent references to the Trinity in the Torah are implicit and not explicit, as Christians claim them to be.

They in fact are not references of any kind. Instead, Christians sought to find references in the Tanakh to the Trinity in order to authenticate and bolster their claims against its plain reading.

Instead, the Torah says exactly what it should have said if it was an angel, which is, "No, offer the sacrifice to God," i.e., not to me.
