*["...2 Samuel 22:2 does not say anything about a rock. I just read it. I'm going to assume you are referring to the word "sel'a" which means "a shadow or shelter". The verse does not apply in the manner you wish it to..."]
***Au contrare...indeed, it DOES say "Rock." Your definition of the word "cela'" [i.e., your spelling 'sel'a"] is INCORRECT and does NOT mean "a shadow or shelter" as you allege. "Cela'" is an Aramaic word that means "craggy rock" according to [STRONGS EXPANDED DICTIONARY OF BIBLE WORDS, page 219, Strong #5553]. Too, the Jewish Publication Society in their 1917 Edition of the Hebrew Bible [i.e., the flagship edition of Jewish Orthodoxy] translates [2 Samuel 22:2-3] from the Hebrew into English as follows:
á åÇéÌÉàîÇø: éÀäåÈä
ñÇìÀòÄé åÌîÀöËãÈúÄé,
{ø} åÌîÀôÇìÀèÄé-ìÄé.
(2) "and he said: The LORD is my ROCK,
and my fortress, and my deliverer;
â àÁìÉäÅé öåÌøÄé,
àÆçÁñÆä-áÌåÉ; {ñ}
îÈâÄðÌÄé åÀ÷ÆøÆï
éÄùÑÀòÄé, {ø}
îÄùÒÀâÌÇáÌÄé åÌîÀðåÌñÄé,
{ñ} îÉùÑÄòÄé, îÅçÈîÈñ
úÌÉùÑÄòÅðÄé. {ø}
(3) "The God who is my ROCK, in Him I take
refuge; my shield, and my horn of
salvation, my high tower, and my refuge;
my SAVIOUR, Thou savest me from
violence."
The INSPIRED Word of God [in BOTH the OT and NT] has just PROVED you to be a DECEIVER and LIAR...who strives to ROB David's and my SAVIOUR [v.3] of His rightful TITLE [ROCK...1 Coreinthians 10:4] and appropriate it to someone else. There is NO DOUBT as to who the ROCK is in ALL of the passages in dispute [1 Samuel 2:2;2 Samuel 22:2;3:3;Psalms 28:1;18:2;89:26].

*["Also, if you believe that Jesus was speaking Greek to Peter and not Aramaic you are stupid considering the evidence to the contrary. Sadly for you, in Aramaic there is no difference in the names."]
***Being the great Catholic apologist that you are it is understandable that you would take the Catholic position that says that the "rock" cannot refer to Jesus, "but only Peter, as is so much more apparent in the Aramaic in which the same word (Kipha) is used for 'Peter' and 'rock'."
The PROBLEM is that the TEXT is NOT in Aramaic, but GREEK. Since we do NOT have the Aramaic TEXT, it is NOT proper NOR scientific to refer to it as PROOF or EVIDENCE of you or your Catholic mentors' position.
Furthermore, in [John 1:42] it says, "He brought him to Jesus. Jesus looked at him, and said, "You are Simon the son of John; you shall be called Cephas," (which is translated Peter." The word "Peter" here is PETROS, not PETRA. It is used to elucidate the Aramaic KEPHAS, which is NOT a NAME in Aramaic. "Except in John 1:42, where it is used to elucidate Aramaic KEPHAS, PETROS is used in the NT ONLY as a NAME for Simon Peter...The translation supports the view that KEPHAS is NOT a proper NAME, since one DOES NOT usually translate proper NAMES" [SOURCE: Liddell, H. (1996). A lexicon: Abridged from Liddell and Scott's Greek-English Lexicon (636). Oak Harbor, WA. Logos Research Systems, Inc.].
The truth is that the ONLY foundation is Jesus. The ONLY rock of truth is Jesus Christ and that we, as His redeemed, need to keep our eyes ONLY on Him. We are to look to NO ONE else as the FOUNDATION, the SOURCE, ot the HOPE in which the Church is built. The Church is built upon Jesus, NOT Peter.
