(Mishnah): A day worker collects all night and a night worker all day. An hourly worker collects all day and all night.

A weekly worker, a monthly worker, a yearly worker, a seven-year worker; if he completed his work in the day, he collects all night; if he completed his work in the night, he collects all day.

(Gemara) - Shmuel: (If a day worker was not paid all night, the next day, the employer transgresses the pasuk (Devarim 24, 15), "...on the same day you shall pay his wage''.

Question (R. Dosa): It is still the same day (as a Jewish day starts and ends at nightfall) and you say that he transgresses, "on his day you shall pay his wage''?

Answer: If your difficulty is in how to understand the pasuk, it can be referring to an hourly worker who works day and night, that he collects all day...

Support (Tosefta): A daytime hourly worker must be paid before the end of that same day; a night-time hourly worker must be paid before the end of that same night. Shmuel was referring to a daytime and night-time hourly worker must be paid that night (for work done that night) and that day (for work done that day and the employer could potentially transgress twice).

(Mishnah): Whether one hired a person, a cow, an animal or utensils, there is a Mitzvah of "on the same day you shall pay his wage'' and a Mitzvah of (Vayikrah 19, 12), "Don't leave the payment of a hired worker until the morning''.

Question: When does he transgress? Only if the worker asked for payment.

If the employer made an agreement with a shopkeeper or a money changer that when the worker needs food or money, they will give him and the employer will pay them back, he does not transgress.

(If the worker asked on time to be paid and the employer claimed that he had already paid it) the worker swears that he still needs to be paid (on time) and he can then take payment. If the time passed, he does not swear and take it. (Rather the employer must swear that he had already paid him and he thereby becomes exempt.) If there are witnesses that the worker asked for the money on time, the worker may swear and then take.

For a Ger Toshav (a gentile living in Eretz Yisrael who accepted upon himself to keep the seven Noachide laws), there is a Mitzvah of "on the same day you shall pay his wage'' but no Mitzvah of, "Don't leave the payment of a hired worker until the morning''.

(Gemara): The pasuk states (Devarim 24, 14), "Do not cheat a poor or impoverished hired person (from amongst your brothers or a stranger who is in your land or someone who is within your gates). "From amongst your brothers'' refers to a Jew; "a stranger'' refers to a convert; "in your land'' includes (when payment is with) animals and slaves; "in your gates'' includes movables.
