DEUT1387 Pay daily laborers their wage at the completion of the work day. Such laborers are usually poor. They need their wages immediately so that they can buy food for themselves and for their families. Therefore, their employers must be punctual in paying their wages. Out of His great kindness, Hashem commands us about the matter to teach us to behave with mercy and concern towards others, and make sure that the needs of the poor are met. Thereby, we perfect our characters and become worthy of Hashem's blessings, which pleases Him, for out of His perfect goodness, He wants to bestow His blessings upon us. See [[LEV369]] Leviticus 19:13 wages CHINUCH 147-8.
