The obligation on the next-of-kin to buy back alienated property was quite as much imposed on him for the sake of the family as of the individual.
The second of his duties was to buy back a member of his family fallen into slavery. 'If a stranger or sojourner with thee be waxen rich, and thy brother be waxen poor beside him, and sell himself unto the stranger... after that he is sold, he may be redeemed; one of his brethren may redeem him.' The price was to vary according to the time which had to elapse before the year of Jubilee, when all slaves were necessarily set free. So Hebrew slavery was entirely unlike the thing called by the same name in other countries, and by virtue of this power of purchase at any time, which was vested in the nearest relative, taken along with the compulsory manumission of all 'slaves' every fiftieth year, came to be substantially a voluntary engagement for a fixed time, which might be ended even before that time had expired, if compensation for the unexpired term was made to the master.
It is to be observed that this provision applied only to the case of a Hebrew who had sold himself. No other person could sell a man into slavery. And it applied only to the case of a Hebrew who had sold himself to a foreigner. No Jew was allowed to hold a Jew as a slave. 'If thy brother be waxen poor with thee, and sell himself unto thee, thou shalt not make him to serve as a bondservant: as an hired servant, and as a sojourner, he shall be with thee.' (Lev. xxv. 39, R. V.).
The last of the offices of the kinsman-redeemer was that of avenging the blood of a murdered relative. If a man were stricken to death, it became a solemn obligation to exact life for life, and the blood-feud incumbent on all the family was especially binding on the next-of-kin. The obligation shocks a modern mind, accustomed to relegate all punishment to the action of law which no criminal thinks of resisting. But customs and laws are unfairly estimated when the state of things which they regulated is forgotten or confused with that of today. The law of blood-feud among the Hebrews was all in the direction of restricting the wild justice of revenge, and of entrusting it to certain chosen persons out of the kindred of the murdered man. The savage vendetta was too deeply engrained in the national habits to be done away with altogether. All that was for the time possible was to check and systematise it, and this was done by the institution in question, which did not so much put the sword into the hand of the next-of-kin as strike it out of the hand of all the rest of the clan.
These, then, were the main parts of the duty of the Goel, the kinsman-redeemer--buying back the alienated land, purchasing the freedom of the man who had voluntarily sold himself as a slave, and avenging the slaying of a kinsman.
II. Notice the grand mysterious transference of this office to Jehovah.
This singular institution was gradually discerned to be charged with lofty meaning and to be capable of being turned into a dim shadowing of something greater than itself. You will find that God begins to be spoken of in the later portions of Scripture as the Kinsman-Redeemer. I reckon eighteen instances, of which thirteen are in the second half of Isaiah. The reference is, no doubt, mainly to the great deliverance from captivity in Egypt and Babylon, but the thought sweeps a much wider circle and goes much deeper down than these historical facts. There was in it some dim feeling that though God was separated from them by all the distance between finitude and infinitude, yet they were nearer to Him than to any one else; that the nearest living relation whom these poor persecuted Jews had was the Lord of Hosts, beneath whose wings they might come to trust. Therefore does the prophet kindle into rapture and triumphant confidence as he thinks that the Lord of Hosts, mighty, unspeakable, high above our thoughts, our words, or our praise, is Israel's Kinsman, and, therefore, their Redeemer. How profound a consciousness that man was made in the image of God, and that, in spite of all the gulf between finite and infinite, and the yet deeper gulf between sinful man and righteous God, He was closer to a poor struggling soul than even the dearest were, must have been at all events dawning on the prophet who dared to think of the Holy One in the Heavens as Israel's Kinsman. No doubt, he was dwelling mostly on historical outward deliverances wrought for the nation, and his idea of Israel's kinship to God applied to the people, not to individuals, and meant chiefly that the nation had been chosen for God's. But still the thought must have been felt to be great and wonderful, and some faint apprehension of the yet deeper sense in which it is true that God is the next-of-kin to every soul and ready to be its Redeemer, would no doubt begin to be felt.
