"Give him his wage on the day it is due"-Deuteronomy 24:15.
We are commanded to pay a daily worker in a timely fashion, and not to delay payment. A day worker collects his wages on the night that follows, and a night worker collects his wages on the following day. This mitzvah applies to all workers-whether Jewish or gentile.
"The wages of a hired worker shall not be left with you overnight until the morning"-Leviticus 19:13.
It is forbidden to delay the timely payment of a hired worker. A day worker must be given his wages on the night that follows, and a night worker on the day that follows.
This prohibition applies only to a Jewish worker (as opposed to the positive commandment to pay in a timely fashion, which applies to both Jewish and non-Jewish workers).
