Deuteronomy 15:10-12

Young's Literal Translation

¹⁰ thou dost certainly give to him, and thy heart is not sad in thy giving to him, for because of this thing doth Jehovah thy God bless thee in all thy works, and in every putting forth of thy hand;

¹¹ because the needy one doth not cease out of the land, therefore I am commanding thee, saying, Thou dost certainly open thy hand to thy brother, to thy poor, and to thy needy one, in thy land.

¹² `When thy brother is sold to thee, a Hebrew or a Hebrewess, and he hath served thee six years -- then in the seventh year thou dost send him away free from thee.
