Śrīmad-Bhāgavatam
[Canto 4, Ch. 14]
niṣīda —just sit down;  iti —thus;  abruvan —they replied;  tāta —my dear Vidura;  saḥ —he;  niṣādaḥ —of the name Niṣāda;  tataḥ —thereafter;  abhavat —became.
TRANSLATION
He was very submissive and meek, and immediately after his birth he bowed down and inquired, “Sirs, what shall I do?” The great sages replied, “Please sit down [niṣīda].” Thus Niṣāda, the father of the Naiṣāda race, was born.
PURPORT
It is said in the  śāstras  that the head of the body represents the  brāhmaṇas , the arms represent the  kṣatriyas , the abdomen represents the  vaiśyas , and the legs, beginning with the thighs, represent the  śūdras . The  śūdras  are sometimes called black or  kṛṣṇa . The  brāhmaṇas  are called  śukla , or white, and the  kṣatriyas  and the  vaiśyas  are a mixture of black and white. However, those who are extraordinarily white are said to have skin produced out of white leprosy. It may be concluded that white or a golden hue is the color of the higher caste, and black is the complexion of the  śūdras .
TEXT 46
तस्य वंशास्तु नैषादा गिरिकाननगोचराः ।  
 येनाहरज्जायमानो येनकत्यषष्ठत्वणम् ॥४६॥
tasya vaṁśyās tu naiṣādā  
 giri-kānana-gocarāḥ  
 yenāharaj jāyamāno  
 vena-kalmaṣam ulbaṇam
tasya —his (Niṣāda’s);  vaṁśyāḥ —descendants;  tu —then;  naiṣādāḥ —called Naiṣādas;  giri-kānana —the hills and forests;  gocarāḥ —inhabiting;  yena —because;  aharat —he took upon himself;  jāyamānaḥ —being born;  vena —of King Vena;  kalmaṣam —all kinds of sin;  ulbaṇam —very fearful.
TRANSLATION
After his [Niṣāda’s] birth, he immediately took charge of all the resultant actions of King Vena’s sinful activities. As such, this Naiṣāda class is always engaged in sinful activities like stealing, plundering and hunting. Consequently they are only allowed to live in the hills and forests.
