אֲחַוֵי כָּל הַלְבְּשׁוּשַׁי גַרְמַי אִנוּן מִסְתַּכְּלִין מְבַזָן לִי.
1. tally my bones | אֲסַפֵּר כׇּל עַצְמוֹתָי – See Ibn Ezra that "אֲסַפֵּר" might be the pi'el form of "אֶסְפּור" (to count). The psalmist does a self-inventory, counting his bones after they have been broken (vs. 15), or perhaps he implies that he is so thin that each bone is visible and able to be counted. Alternatively, "אֲסַפֵּר" means to recount, and the psalmist says that he spoke about his bones, i.e. about his pain. Cf. Radak that "עַצְמוֹתָי" does not mean "bones" here, but rather "arguments", pointing to the similar "עֲצֻמוֹתֵיכֶם" of Yeshayahu 41:21, which refers to disputes or claims. [See also usage of the verb "עצם" in Mishnaic Hebrew (שנים שהיו מתעצמים בדין) and perhaps, Mishlei 18:18.] The psalmists states that when he comes to lay forth his complaints to his enemies, he is looked at with scorn.
2. stare at me | יִרְאוּ בִי – See Malbim that any time the root "ראה" is followed by the preposition "ב", the connotation is that one is looking at another in derision. Cf. R. Moshe ibn Chiquitilla, that such usage indicates rejoicing, pointing to Tehillim 106:5 where the "לִרְאוֹת בְּ" is parallel to "לִשְׂמֹחַ בְּ". Here, the connotation would be: "they rejoiced at my misfortune".
