This is the fourth use of T'hillim / Psalm 40 by the list maker. The subject of the psalm admits to being guilty of sin (worse than sin -- iniquity!). If Jesus was "without sin" then how can this psalm be about him?
Now the list maker states that Jesus "fulfilled" a prophecy in this psalm (psalms are not prophecy) that the messiah would be confronted by adversaries in "the" garden (not even "a" garden).
Where in the psalm does it say that the subject is confronted by his enemies in a garden?
T'hillim / Psalm 40 begins with the words "For the conductor, of David a song." This is another psalm written by and about (autobiographical) King David. In line 15 (14 in Christian versions most of which either eliminate the first line or don't number it) says: "May those who seek נַפְשִׁי / nafshi (my life) to destroy it be shamed and embarrassed together; may those who seek to harm me retreat and be humiliated."
Most translations have "my soul" in this verse, but in reality it is "my life" and not "my soul."
The Hebrew word נַפְשִׁי / nafshi translates to "my life", not immortal soul. Most non-Hebrew speakers (reading in English) think that this line is speaking of the immortal “soul” since most translations translate it as "soul." This misleads innocent readers into thinking that this line is about the immortal soul, when in reality it is for about the "soul" (e.g. blood coursing) through your veins -- your life-force.
נַפְשׁוֹת nafshot (plural) or נֶֽפֶשׁ nefesh (singular) always refers to life force. Look up נַפְשׁוֹת in a translator (like Google Translate) and it is translated as "people." When you read the T'nach you'll see that even plants and animals possess a נֶֽפֶשׁ nefesh -- see B'reshit / Genesis 1:30 and 6:17 -- this is NOT the immortal soul. The immortal soul is from the ru'ah that G-d breathed into man (B'reshit / Genesis 2:7). Some translate נֶֽפֶשׁ nefesh as "the soul of the FLESH" -- meaning not the immortal soul, but what is a "soul of the flesh" but that which keeps you physically alive!
Ergo David is speaking of G-d saving his PHYSICAL life in verse 15 -- not his immortal soul.
T'hillim / Psalm 40 (and many other psalms) are speaking of the נֶפֶשׁ nefesh -- the living human being.
King David is speaking of his hopes that those who seek to kill him be disgraced. Those who rejoice over his misfortunes should be astounded by their own misfortunes for turning on him. David then says that those who faithfully pursue G-d should be rewarded with joy in Him and always praise Him for His salvation.
Salvation has nothing to do with an immortal soul either. In the T'nach (Jewish bible) it always refers to being rescued (saved) from danger -- again the physical life, not the immortal soul. . .
This psalm has nothing to do with a prophecy about the messiah being confronted by adversaries -- again that is such a universal experience (haven't we all felt confronted by people who dislike us at some point) that this is too broad a thing to ever be considered a true messianic prophecy.
Next we'll be told that eating a meal is a messianic prophecy because it is mentioned in the T'nach and Jesus ate something once in his life. Just how silly are these "prophecies" going to continue to be?
