50He then with his purchaserH7069 shall calculateH2803 from the yearH8141 when he soldH4376 himself to him up to the yearH8141 of jubileeH3104; and the priceH3701 of his saleH4465 shall correspondH1961 to the numberH4557 of yearsH8141. It is like the daysH3117 of a hiredH7916 manH7916 that he shall be with him.

51IfH518 there are stillH5750 manyH7227 yearsH8141, 1he shall refundH7725 part of his purchaseH4736 priceH3701 in proportionH6310 to them for his own redemptionH1353;

52and ifH518 fewH4592 yearsH8141 remainH7604 untilH5704 the yearH8141 of jubileeH3104, he shall so calculateH2803 with him. In proportionH6310 to his yearsH8141 he is to refundH7725 the amount for his redemptionH1353.
