Is it permissible to work in a non-Islamic bank to pay off a debt of 7,0 Jordanian Dinars?

It is not permissible to work in an interest-based bank to pay off debt or for any other reason, due to the severe warnings against usury and dealing with it. A small amount that is lawful is more beneficial and blessed than a large amount that is unlawful. One can search for another permissible job with a higher income, while fearing Allah and asking Him to bless what He has given, and supplicating for the repayment of the debt.
