1If there is a controversy between men, and they come to judgment and the judges judge them, then they shall justify the righteous and condemn the wicked. 2It shall be, if the wicked man is worthy to be beaten, that the judge shall cause him to lie down and to be beaten before his face, according to his wickedness, by number. 3He may sentence him to no more than forty stripes. He shall not give more, lest if he should give more and beat him more than that many stripes, then your brother will be degraded in your sight.
4You shall not muzzle the ox when he treads out the grain.
5If brothers dwell together, and one of them dies and has no son, the wife of the dead shall not be married outside to a stranger. Her husband’s brother shall go in to her, and take her as his wife, and perform the duty of a husband’s brother to her. 6It shall be that the firstborn whom she bears shall succeed in the name of his brother who is dead, that his name not be blotted out of Israel.
7If the man doesn’t want to take his brother’s wife, then his brother’s wife shall go up to the gate to the elders, and say, “My husband’s brother refuses to raise up to his brother a name in Israel. He will not perform the duty of a husband’s brother to me.” 8Then the elders of his city shall call him, and speak to him. If he stands and says, “I don’t want to take her,” 9then his brother’s wife shall come to him in the presence of the elders, and loose his sandal from off his foot, and spit in his face. She shall answer and say, “So shall it be done to the man who does not build up his brother’s house.” 10His name shall be called in Israel, “The house of him who had his sandal removed.”
11When men strive against each other, and the wife of one draws near to deliver her husband out of the hand of him who strikes him, and puts out her hand, and grabs him by his private parts, 12then you shall cut off her hand. Your eye shall have no pity.
13You shall not have in your bag diverse weights, one heavy and one light. 14You shall not have in your house diverse measures, one large and one small. 15You shall have a perfect and just weight. You shall have a perfect and just measure, that your days may be long in the land which Yahweh your God gives you. 16For all who do such things, all who do unrighteously, are an abomination to Yahweh your God.
17Remember what Amalek did to you by the way as you came out of Egypt, 18how he met you by the way, and struck the rearmost of you, all who were feeble behind you, when you were faint and weary; and he didn’t fear God. 19Therefore it shall be, when Yahweh your God has given you rest from all your enemies all around, in the land which Yahweh your God gives you for an inheritance to possess it, that you shall blot out the memory of Amalek from under the sky. You shall not forget.
Based on God’s covenant relationship with Israel, "goel" (translated as "kinsman-redeemer") refers to the relative who is obliged to restore the fortunes of disadvantaged family members. The goel's responsibilities included: 1) To marry his brother's widow and produce an heir (Deut 25:5-10); 2) To avenge the murder of the nearest relative (Num 35:11-28); 3) To buy back the family land that a kinsman had sold (Lev 25:25); 4) To take care of the needy members of the family (Lev 25:35); 5) To buy back a kinsman who had been sold as a slave (Lev 25:47-49).
At the refusal of the nearest goel to redeem Elimelech's land and marry Ruth in the manner of levirate marriage, Boaz, being the next near relative (Ruth 2:20), accepted the honor and duty of goel.
The theological significance of "goel" is that as redeemer of Israel (Exod 6:6-7) the Lord is concerned about the poor, needy and oppressed (Prov 23:10-11; Ps 68:5-6; 72:2-4). The New Testament sees Jesus Christ as kinsman-redeemer for humanity (Gal 4:4-7 See also Gal 3:13-14; Heb 2:11-18). Boaz, a distant ancestor in Jesus' family line, thus serves as a foreshadow of Jesus' role for the world.
