"and he shall serve him forever": until the Jubilee year (Yovel). For it would follow otherwise, viz.: If money, whose "power" is formidable, and which acquires everything, acquires only for six years, then boring, which acquires only bondsmen, how much more so should it acquire (a bondsman) for only six years! It is, therefore, written "and he shall serve him forever"—until the Yovel. But perhaps the meaning is that he acquires him forever—literally! It is, therefore, (to negate this) written (Leviticus 25:10) "And (in the Yovel) you shall return a man (including a bored bondsman) to his holding."
