전도서 12:2의 Musar

ולא תלין פעולת שכיר אתך עד בוקר . The reason one is not allowed to delay paying wages to a day laborer till the morning following (19,13) is that G–d arranges sustenance for each of His creatures and the laborer in question was allocated these wages by G–d to use them for his food supply this very day. By denying him access to this the employer effectively interfered with G–d's decree and the angel appointed to oversee allocation of sustenance on that day will turn into an accuser against the employer in question. He will be judged as having transgressed a Royal decree. The domain which will judge the employer is the attribute of night, [an attribute applying justice rigorously. Ed.] The Torah (Deut. 24,15) describes the state of mind of the laborer in question in the words: ואליו הוא נושא את נפשו, "And his life depends on it."
