Ruth 2:1; 3:10-18; 4:1-10
The kinsman Redeemer: The word “Gawl” is used in Old Testament for the Redeemer as well as for Kinsman … the one who pays the debt, or the next of kin.
The case of Boaz and Ruth is a perfect example and is a beautiful type of Christ.
It comes from the Mosaic law of Redemption and pictures the coming Christ.
Leviticus 25:47-49, “And if a sojourner or stranger wax rich by thee, and thy brother that dwelleth by him wax poor, and sell himself unto the stranger or sojourner by thee, or to the stock of the stranger’s family: After that he is sold he may be redeemed again; one of his brethren may redeem him: Either his uncle, or his uncle’s son, may redeem him, or any that is nigh of kin unto him of his family may redeem him; or if he be able, he may redeem himself.”
And again in Isaiah 59:20-21, “And the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the LORD. As for me, this is my covenant with them, saith the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed’s seed, saith the LORD, from henceforth and for ever.”
Then as you read the New Testament we find that:
Romans 11:26, “And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob.”
Galatians 4:5, “To redeem them that were under the law, that we might receive the adoption of sons.”
