Deuteronomy 24:15

15 but in the same day thou shalt yield to him the price of his travail, before the going down of the sun, for he is poor, and sustaineth thereof his life; lest he cry against thee to the Lord, and it be reckoned to thee into sin. (but thou shalt yield to him the wages for his work on the same day, before the going down of the sun, for he is poor, and sustaineth his life with them; lest he cry against thee to the Lord, and it be reckoned unto thee as a sin.)

Deuteronomy 24:15 Meaning and Commentary

Deuteronomy 24:15

At his day thou shalt give [him] his hire
At the close of the day, when his work is done, the hire agreed for must be paid him; and, by the same rule, all such that were hired by the week, month, or year, were to have their wages paid them at the day their time was up:

neither shall the sun go down upon it;
it was to be paid before sun setting, or at it; see ( Leviticus 19:13 ) ;

for he [is] poor, and setteth his heart upon it;
being poor, he cannot wait any longer for the payment of it; his personal and family wants are such as require immediate payment; and besides, he has been eagerly expecting it, and earnestly desiring it, that he may satisfy the craving necessities of himself and family; and therefore it would be a great balk and disappointment to him to have his wages detained:

lest he cry against thee to the Lord;
having none to apply unto but him, who is the patron of the poor and needy, not being able to help himself, nor having interest in any to interpose on his behalf; and his cry, and the cry of his hire too, enter into the ears of the Lord of hosts, and is regarded by him, ( James 5:4 ) ;

and it be sin unto thee:
be imputed to him, the guilt charged on him, and punishment inflicted for it.

Deuteronomy 24:15 In-Context

13 but anon thou shalt yield his wed to him before the going down of the sun, that he sleep in his cloth, and bless thee, and thou have rightwiseness before thy Lord God. (but at once thou shalt yield his pledge back to him, yea, before the going down of the sun, so that he can sleep in his own cloak, and bless thee, and then thou shalt have righteousness before the Lord thy God.)

14 Thou shalt not deny the hire of thy brother (who is) needy and poor, either of the comeling that dwelleth with thee in thy land, and is within thy gates; (Thou shalt not withhold the wages of thy servant who is needy and poor, whether he be a fellow Israelite, or a newcomer who dwelleth with thee in thy land, within thy gates;)

15 but in the same day thou shalt yield to him the price of his travail, before the going down of the sun, for he is poor, and sustaineth thereof his life; lest he cry against thee to the Lord, and it be reckoned to thee into sin. (but thou shalt yield to him the wages for his work on the same day, before the going down of the sun, for he is poor, and sustaineth his life with them; lest he cry against thee to the Lord, and it be reckoned unto thee as a sin.)

16 The fathers shall not be slain for the sons, neither the sons for the fathers, but each man shall die for his own sin.

17 Thou shalt not waywardly turn, or mis-deem, the doom of the comeling, or of the fatherless, either motherless child; neither thou shalt take away instead of a wed the cloth of a widow. (Thou shalt not waywardly turn, or pervert, justice for the newcomer, or for the fatherless or the motherless child; nor shalt thou take away the cloak of a widow in place of a pledge.)
