Leviticus 25:29
And if a man sell a dwelling house in a walled city, then he may redeem it within a whole year after it is sold; within a full year may he redeem it. And if a man sell a dwelling house in a walled city, then he may redeem it within a whole year after it is sold; within a full year may he redeem it.
The verse belongs to the Leviticus instructions about duties of one to another, given as special directions for a brother fallen into decay. It was communicated from heaven by the Lord over the whole earth, spoken by Christ through Moses to Israel, and embodies the principles of Christianity and the gospel of the Old Testament. It is actual practical missionary work, not mere theory.
It stands with the every-seventh-year sabbath, when cultivation of the soil was forbidden and the land lay in spontaneous growth for the benefit of the poor, with free access for strangers and for flocks and herds to invigorate worn-out soil, and with the fiftieth-year jubilee. Together with those laws it teaches that God is the householder and owner of the land and the people are His tenants, that He makes the land productive and blesses lands when they are obedient, and that He cares for the poor by special provision, even making the sixth year yield enough for three years, to encourage liberality and overcome stinginess and selfishness. Its specific requirement is that the poor brother, even a stranger or sojourner, must be relieved so he may live, with money and food given without usury or increase.
It continues to the present time as binding duty and practical home missionary work, to be brought into practical life and worked out intelligently in obedience. Refusing to hear and do it is sin when the poor cry to the Lord, prayers are not accepted as pleasing worship, prosperity is removed for unjust and unmerciful dealing, and the charge rests on God's people unless those in responsible positions unite to see the work done. Applied in this age of great light, it requires hearts not full of selfish principles but open to help brethren laboring in hard fields rather than closing the heart and refusing help.
