Legally, if you are not paid for  work you did, you may sue the employer for the money; you are under no obligationt to "bear with them" and they have no right to make you wait. While it may be impossible to recover the money if the employer truly is running out of funds, the longer you wait, likely the worse their financial position will be if they are encountering difficulties (e.g. what money they have may be used up over time, and they may shut their doors, go out of business, etc.). Therefore, you may wish to consider bringing an action soon, if they don't make good their arrears on demand from you.
