First, notice that the claimed "prophecy" does not reference an entire sentence -- but only the second part of the sentence. Odd, don't you think?
The context is unimportant to the list maker -- they are simply trying to match together a round peg into whatever hole they can force it -- as if having wisdom somehow makes a person a god, let alone a messiah (anointed one).
Yet again we have the list maker taking a really broad claim -- in this case speaking the wisdom of G-d -- which all of the prophets of the T'nach have done (they all relayed direct messages from G-d to the people of their generation) and somehow claim that this is unique to Jesus.
Not to mention that the psalm makes no mention of the author (or subject) of this verse having authority (and authority from WHOM pray tell?).
Matthew 7:29 says "for he was teaching them as one who had authority, and not as their scribes." -- yet by whose authority did Jesus speak? It is well and good for Jesus and / or his followers to claim to be a god or a messiah -- but where is the proof?
As a general rule, no single witness alone is competent to attest or testify: there must always be at least two (D'varim / Deut. 19:15; Sif. Deut. 188; Sot. 2b; Sanh. 30a; Yad, Edut 5:1). Where are there two witnesses to the fact that G-d (or some court of Jewish law) gave Jesus the authority to speak for G-d?
Even if one looks at the claim that G-d's voice said He was "well pleased" with Jesus in Matthew 3:17 or Mark 1:11 all we have is someone (John? Jesus?) hearing a voice. Did he (singular) hear the voice of G-d? Did he hear a demon trying to fool him? Did he merely hallucinate hearing a voice?
And John (or Jesus) is one person.
There are no two witnesses.
D'varim / Deuteronomy 13 warns us “If there should stand up in your midst a prophet or a dreamer of a dream, and he will produce to you a sign or a wonder, and the sign or the wonder comes about, of which he spoke to you, saying "Let us follow gods of others that you did not know (at Sinai) and we shall worship them do not hearken to the words of that prophet or to that dreamer of a dream, for HASHEM, your G-d, is testing you to know whether you love HASHEM, your G-d with all your heart and with all your soul. HASHEM, your G-d, shall you follow and Him shall you fear; His commandments shall you observe and to His voice shall you hearken; Him shall you serve and to Him shall you cleave. And that prophet and that dreamer of a dream shall be put to death, for he had spoken perversion against HASHEM, your G-d Who takes you out of the land of Egypt, and Who redeems you from the house of slavery to make you stray from the path on which HASHEM, you G-d, has commanded you to go; and you shall destroy the evil from your midst.” (Artscroll Stone Edition Chumash) D’varim / Deuteronomy 13:2-6.
The mere claim of someone having a personal revelation is worthless says the Torah -- if that claim in any way contradicts the Torah. A man claiming to be G-d, or even the son of G-d (a demi-god) is reversing the Torah and is thus false.
Ask yourself, why should you believe an individual's revelation whether it is from the Christian bible, the Book of Mormon or the Koran? The Torah warns us time and again not to be led astray and to not follow any "god" or "strange worship" that we did not know at Sinai -- and that includes worshiping Jesus as a god, or even a "son" of G-d.
T'hillim / Psalm 78 is "a maskil of אָסָף / Asaph. Hearken, my people, to my instruction, extend your ear to the words of my mouth." This is the first line -- and it makes it clear that this poem is by אָסָף / Asaph, and it is Asaph who is speaking in parables -- not Jesus. Asaph is mentioned in נְחֶמְיָה / Nehemiah 12:46 (quoted above) as well as Divrei Hayamim Alef / 1 Chronicles 6:24.
אָסָף / Asaph was writing a historical psalm about Jewish history spanning from our freedom from Egyptian slavery through the crowning of David as king.
So, yet again we have the list maker misapplying a passage, lifting it out of context, and claiming that somehow Jesus "fulfilled" something that is, in this case, historical fact not prophecy about a future messiah.
As mentioned in my last post on this list, many people in the bible spoke in parables. Simply speaking in parables does not mean a passage is about Jesus -- and the psalm itself says nothing about the author (Asaph) speaking with the authority, direct or otherwise, of G-d. Psalms are found in Ketuvim (Writings) and express the worsd of the author, who may be inspired by G-d but the person is not relaying a direct message from G-d (which would be prophecy).
