Leviticus 25:51

And if any have a greater number of years [than enough], according to these he shall pay his ransom out of his purchase-money.

If there be yet many years behind, according unto them he shall give again the price of his redemption out of the money that he was bought for.

If there are yet many years, according to them he shall give back the price of his redemption out of the money that he was bought for.
