Hebrew OT translation to Greek NT

Well, this is actually not an answer but more a comment to an answer previously given (or additional question) that I cannot submit otherwise as my reputation is not high enough. Please forgive me and feel free to correct me.... However..

Can anyone please point me to a source where I can see the Hebrew words for 'az gevah' (body) and 'oznayim' (ears) in order to see the plausibility of Kennicott/Clarke's explanation that "The Hebrew words "then a body" (az gevah) could have been carelessly copied as "ears" (oznayim), which look very similar in the Hebrew."?

EDIT: This diagram might answer the question by visually complementing the Kennicott/Clarke's explanation:

Thank you.

The author is quoting the Septuagint:

This is apparently, a poor translation from the original Hebrew to the Greek. There are several examples of translation issues in the Septuagint. This is another example of such a translation.

The author of Hebrews is quoting from the Septuagint, which apparently mistranslated or poorly translated Psalm 40:6.

This brings up issues of infallibility (e.g., is the mistranslation inspired because it's in an inspired book?). This doesn't totally resolve the problem, but I tend to look at issue like this as confirmation that the Holy Spirit is powerfully at work in us when we read the Scriptures, and that is more important than having the most accurate translation possible. Many centuries of Christians were without good translations of the Bible, and they got on remarkably well.

edit in response to comment: As @cwallenpoole points out, there is an alternative interpretation. Perhaps the author of Hebrews was quoting from an earlier, more accurate Hebrew text that is no longer extant (or perhaps he was quoting from the septuagint, which was itself based on a more accurate Hebrew text), as discussed here.

The footnote for Hebrews 10:5-7 in the New American Bible mentions the following:

A passage from Ps 40:7–9 is placed in the mouth of the Son at his incarnation. As usual, the author follows the Septuagint text. There is a notable difference in Heb 10:5 (Ps 40:6), where the Masoretic text reads “ears you have dug for me” (“ears open to obedience you gave me,” NAB), but most Septuagint manuscripts have “a body you prepared for me,” a reading obviously more suited to the interpretation of Hebrews.

The original and ostensibly mistranslated passage appears in the Septuagint. Why this translation appears in the Septuagint and not the Masorectic text is something of a mystery, but there are a few different conjectures that discount the Masorectic text's translation. Notably by Benjamin Kennicott as descibed by Adam Clarke:

Dr. Kennicott has a very ingenious conjecture here: he supposes that the Septuagint and apostle express the meaning of the words as they stood in the copy from which the Greek translation was made; and that the present Hebrew text is corrupted in the word oznayim, ears, which has been written through carelessness for az gevah, THEN A BODY. The first syllable THEN, is the same in both; and the latter which joined to makes oznayim, might have been easily mistaken for gevah, BODY; nun, being very like gimel; yod, like vau; and he, like final mem; especially if the line on which the letters were written in the MS. happened to be blacker than ordinary, which has often been a cause of mistake, it might have been easily taken for the under stroke of the mem, and thus give rise to a corrupt reading: add to this the root carah, signifies as well to prepare as to open, bore, Septuagint, and followed by the apostle, must have read the text thus: az gevah caritha li, σωμαδεκατηρτισωμοι, then a body thou hast prepared me: thus the Hebrew text, the version of the Septuagint, and the apostle, will agree in what is known to be an indisputable fact in Christianity, namely, that Christ was incarnated for the sin of the world.

That is, Psalms 40 in the Masorectic text has a transcription error that was not present in the translations upon which the Septaguint manuscripts were based.
