Hebrew · Sifrei Devarim (Hebrew)והיה לך עבד עולם. כל ימי עולמו של אדון - אף [אם] הוא נמכר ל' שנה ומ' שנה לפני היובל. מכאן אתה אומר, עבד עברי עובד את הבן ואינו עובד את הבת. נרצע ונמכר לעכו"ם - אינו עובד לא את הבן ולא את הבת. מנין ליתן את האמור של זה בזה, ואת האמור של זה בזה? תלמוד לומר עבד עולם , "עולם" "עולם" לגזרה שוה.
English · Shraga Silverstein"and he shall be unto you a servant forever" — the "forever" of Yovel. — But, perhaps, "forever" literally! — It is, therefore, written (Vayikra 25:10) "And each one of you will return to his holding" (at the Yovel). Why, then, is it written "a servant forever"? For I might think that (after his ear is bored) he serves only six years, so that his end (i.e., the end of his servitude) not be graver than his beginning; it is, therefore, written "a servant 'forever'" — even thirty years, even forty, until the Yovel. "and he shall be unto you a servant forever," and, elsewhere, (Vayikra 21:5) "and he shall serve him forever" — not his son and not his daughter — whence it is ruled: A Hebrew man-servant serves the son, but not the daughter. One whose ear was bored and one who was sold to a gentile serves neither the son nor the daughter. Whence is it derived that what is stated here (Devarim) applies there (Vayikra), and what is stated there applies here? From "forever" (Devarim 15:17) - "forever" (Vayikra 21:5), for an identity (gezeirah shavah ).
