Widow

Boyd’s Bible Dictionary:

(lack). When a married man died without children, his brother, if still living with the family, had a right under the law to marry the widow in order to preserve the family name and inheritance (Deut. 25:5-6⁵If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of an husband's brother unto her. ⁶And it shall be, that the firstborn which she beareth shall succeed in the name of his brother which is dead, that his name be not put out of Israel. (Deuteronomy 25:5‑6); Matt. 22:23-30²³The same day came to him the Sadducees, which say that there is no resurrection, and asked him, ²⁴Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother. ²⁵Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother: ²⁶Likewise the second also, and the third, unto the seventh. ²⁷And last of all the woman died also. ²⁸Therefore in the resurrection whose wife shall she be of the seven? for they all had her. ²⁹Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. ³⁰For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. (Matthew 22:23‑30)). Other provisions of the Mosaic law show great consideration for widows (Ex. 22:22²²Ye shall not afflict any widow, or fatherless child. (Exodus 22:22); Deut. 14:29; 16:11,14; 24:19-21; 26:12; 27:19²⁹And the Levite, (because he hath no part nor inheritance with thee,) and the stranger, and the fatherless, and the widow, which are within thy gates, shall come, and shall eat and be satisfied; that the Lord thy God may bless thee in all the work of thine hand which thou doest. (Deuteronomy 14:29)
¹¹And thou shalt rejoice before the Lord thy God, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates, and the stranger, and the fatherless, and the widow, that are among you, in the place which the Lord thy God hath chosen to place his name there. (Deuteronomy 16:11)
¹⁴And thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite, the stranger, and the fatherless, and the widow, that are within thy gates. (Deuteronomy 16:14)
¹⁹When thou cuttest down thine harvest in thy field, and hast forgot a sheaf in the field, thou shalt not go again to fetch it: it shall be for the stranger, for the fatherless, and for the widow: that the Lord thy God may bless thee in all the work of thine hands. ²⁰When thou beatest thine olive tree, thou shalt not go over the boughs again: it shall be for the stranger, for the fatherless, and for the widow. ²¹When thou gatherest the grapes of thy vineyard, thou shalt not glean it afterward: it shall be for the stranger, for the fatherless, and for the widow. (Deuteronomy 24:19‑21)
¹²When thou hast made an end of tithing all the tithes of thine increase the third year, which is the year of tithing, and hast given it unto the Levite, the stranger, the fatherless, and the widow, that they may eat within thy gates, and be filled; (Deuteronomy 26:12)
¹⁹Cursed be he that perverteth the judgment of the stranger, fatherless, and widow. And all the people shall say, Amen. (Deuteronomy 27:19)).
