Here is my understanding of what is going on. Ka’ari or ka’aru that is the question.
For the Tanakh they translate the word ka’ari, literally the last part of the verse: like a lion my hands and my feet
This is a strange bit of scripture even in the Hebrew. Unfortunately, to make it make some kind of sense (or to be contrary to Christians interpretations

, words have been added to the Tanakh that are not there: “they are at”
And Christian texts translate this strange bit of verse with the the word pierced. They are not wrongly translating the word on purpose, but are translating an entirely different word all together. The word ka’aru, “pierced” would then be correct.
Now which is correct in the original hebrew, ka’ari or ka’aru? Well some of the sources of original hebrew texts have the word ka’ari and some have the word ka’aru.
Well let’s look to something unbiased from either side: The Dead Sea Scrolls. They use the word ka’aru.
So there is a witness for the word pierced. But who can read the entire psalm and not see in the text the suffering of the Messiah?
