50And he shall reckon with him that boughtH7069 him from the yearH8141 that he wasH1961 soldH4376 to him unto the yearH8141 of jubileeH3104; and the price of his saleH4465 shall beH1961 according to the numberH4557 of the yearsH8141, according to the daysH3117 of a hired servant shall he beH1961 with him.

51If there are yetH5750 manyH7227 yearsH8141, according unto them shall he returnH7725 his redemptionH1353 [moneyH3701] out of the moneyH3701 that he was bought for;

52and if there remainH7604 but fewH4592 yearsH8141 unto the yearH8141 of jubileeH3104, then he shall reckon with him; according unto his [remainingH7604] yearsH8141 [of service] shall he give him backH7725 his redemptionH1353 [money].
