At his day thou shalt give him his hire, neither shall the sun go down upon it; for he is poor, and setteth his heart upon it: lest he cry against thee unto the LORD, and it be sin unto thee. He is poor, and setteth his heart upon it - How exceedingly natural is this! The poor servant who seldom sees money, yet finds from his master's affluence that it procures all the conveniences and comforts of life, longs for the time when he shall receive his wages; should his pay be delayed after the time is expired, he may naturally be expected to cry unto God against him who withholds it. See most of these subjects treated at large on Exodus 22:21-27 (note).
