Deuteronomy 15:18-20

Young's Literal Translation

¹⁸ `It is not hard in thine eyes, in thy sending him away free from thee; for the double of the hire of an hireling he hath served thee six years, and Jehovah thy God hath blessed thee in all that thou dost.

¹⁹ `Every firstling that is born in thy herd and in thy flock -- the male thou dost sanctify to Jehovah thy God; thou dost not work with the firstling of thine ox, nor shear the firstling of thy flock;

²⁰ before Jehovah thy God thou dost eat it year by year, in the place which Jehovah doth choose, thou and thy house.
