How will we reconcile "be'Yomo Titein Secharo" with the Pasuk in Vayikra 19:13 "ve'Lo Salin Pe'ulas Sachir ad Boker"?
Torah Temimah (citing Bava Metzi'a, 110b): The current Pasuk is referring to a day worker, whose remuneration is due by the end of the following night; whereas the Pasuk in Kedoshim is speaking about a night worker, who needs to be paid by the end of the following day.
What are the connotations of "ve'Eilav hu Nosei es Nafsho"?
Rashi: It means that the worker (sometimes) endangers himself climbing up a ramp and suspending himself from a tree - for his wages.
Rashbam: He means that the worker has a strong desire 1 (sets his mind on) for his wages.
Why does the Torah write "ve'Lo Yikra Alecha el Hashem"?
Since the Torah writes "Vehayah b'cha Chet", why did it also need to write "ve'Lo Yikra Alecha el Hashem."
Rashi: To teach us that Hashem will hasten to punish sooner, if the laborer cries out to Him.
