sources mekorot - Is there any significance in the 10th of Rambam's 13 Principles of Faith quoting a Passuk?

If you read Rambam's 13 Ani Maamin's, 13 Principles of Faith, you'll note that only the 10th one makes reference to Tanach. Is there a reason for that? (Looking for sourced answer, rather than speculation).

י] אֲנִי מַאֲמִין בֶּאֱמוּנָה שְׁלֵמָה, שֶׁהַבּורֵא יִתְבָּרַךְ שְׁמו יודֵעַ כָּל מַעֲשה בְנֵי אָדָם וְכָל מַחְשְׁבותָם, שֶׁנֶּאֱמַר הַיּצֵר יַחַד לִבָּם הַמֵּבִין אֶל כָּל מַעֲשיהֶם.

I believe with perfect faith that the Creator, Blessed be His Name, knows all the deeds of human beings and all their thoughts, as it is written, "Who fashioned the hearts of them all, Who comprehends all their actions" (Psalms 33:15).
