Deuteronomy 15:17-19 Darby Translation (DARBY)
17 then thou shalt take an awl, and thrust it through his ear and into the door; and he shall be thy bondman for ever. And also unto thy handmaid thou shalt do likewise.
18 Let it not seem hard unto thee, when thou sendest him away free from thee; for double the worth of a hired servant hath he been to thee, [in] serving thee six years; and Jehovah thy God will bless thee in all that thou doest.
19 Every firstling that is born among thy kine and among thy sheep that is a male, thou shalt hallow to Jehovah thy God: thou shalt do no work with the firstling of thy kine, nor shear the firstling of thy sheep.
