Rashi: Lame people gathered to me.
Rashi citing Menachem: This is like "Necha'im" (Yeshayah 16:7; broken people).
Radak: Lowly people gathered to me. The same applies to "Bnei Naval Gam Bnei Vli Shem Nik'u Min ha'Aretz" (Iyov 30:8). I.e. they are lame and pressed from their lowliness.

Bava Metzi'a 59a: David said 'if I would be torn, my blood would not spill 1 .' Even when my tormentors are learning about Tzara'as and Tum'as Ohel, they ask me 'which death penalty is given for Bi'ah with a married woman 2 ?'
Radak #1: They tore their mouths amidst great laughter, and they were not silent from jesting about me.
Radak #2: Kar'u is an expression of opening, like "v'Kar'u Lo Chalonai" (Yirmeyah 22:14).
Radak #3: When they slander me, it is as if they tore my flesh.
Radak citing his father: They tore what cannot be sewn, [even] if they will regret. This is a metaphor for evil deeds and words.
Malbim: Amidst their great desire that I die, they tore their garments, as if I was dead, but they were not silent like people normally tear amidst silence and mourning.
