Matthew Poole and continuators on Deuteronomy 15:17

17 Then thou shalt take an awl, and thrust it through his ear unto the door, and he shall be thy servant for ever : and also unto thy maidservant thou shalt do likewise .

(i. e.) All the time of his Life, or, at least, till the year of Jubile. See on Exod. 21. 6.

(i. e.) Either dismiss her honourably and with plenty of provision: or engage her to perpetual servitude in the same manner and by the same Rites. Whence it appears, that this case differs from that Exod. 21. 7. and that the maid-servant there was taken in upon other and better terms than this here.
