Bible Verses About Masters: Not to keep back their wages

Thou shalt not calumniate thy neighbour, nor oppress him by violence. The wages of him that hath been hired by thee shall not abide with thee until the morning.

But thou shalt pay him the price of his labour the same day, before the going down of the sun, because he is poor, and with it maintaineth his life: lest he cry against thee to the Lord, and it be reputed to thee for a sin.
