(Devarim 15:4) "But there shall not be in you a poor man.": And elsewhere it is written (Ibid. 11) "For a poor man shall not cease from the midst of the land!" — When you do the L-rd's will, the poor will be among the gentiles, and when you do not do His will, the poor will be among you.
Will There Be No Poor or Will the Poor Never Cease
Sifrei Devarim 114:1
