Dye your thirst, dye your thirst, dye your thirst
Kendrick suggest that you should turn your negatives into positives. A few bars earlier he says that he is dying of thirst (check the wordplay on dye and die).
However, when you dye something, you change it’s appearance. He’ll show you how to kill your thirst for sin.
And from the previous bar, flowers are never truly black, so the only way to have a black flower is to dye it.
