四分律比丘含注戒本 2.13

2.13

有多種，卑姓家生，行業亦卑，伎術工巧亦卑，或言「汝犯過」，或言「多結使」，或言「盲」「瞎」等語也。

There are many kinds: being born into a low-caste family, one's livelihood and conduct being low, or one's crafts and skills being low; or saying, "You committed a fault," or saying, "You have many fetters," or words such as "blind," "one-eyed," and so forth.
