I don't want a lifetime sentence
Bleek is actually only metaphorically referring to jail time here, the life sentence he means is one of being trapped as a low level drug dealer just barely making enough money to live comfortably
This coupled with the “Just give me the word” lyric is a triple entendre. Jail time and selling drugs makes it a double entendre. Then he says he doesn’t want a lifetime sentence [a literal sentence that is filled with words as a metaphor for his life]….just give me the word…so he just wants to do it for a part of his life. A word is only part of a sentence.
