Leviticus 25:47

''If an alien or a temporary resident among you becomes rich and one of your countrymen becomes poor and sells himself to the alien living among you or to a member of the alien's clan,

(New International Version)

'Now if the means of a stranger or of a sojourner with you becomes sufficient, and a countryman of yours becomes so poor with regard to him as to sell himself to a stranger who is sojourning with you, or to the descendants of a stranger's family,

(New American Standard Bible)

And if a sojourner or stranger wax rich by thee, and thy brother that dwelleth by him wax poor, and sell himself unto the stranger or sojourner by thee, or to the stock of the stranger's family:

(King James Version)
