Midrash su Levitico 25:50

2) R. Shimon says: Whence is it derived that theft of a gentile is "theft" (and forbidden)? From (Vayikra 25:48) "After he is sold, (monetary) redemption shall there be for him" — he shall not be seized (from the gentile without payment). I might think that he may fool him (the gentile into letting him go for a token payment); it is, therefore, written (Vayikra 25:50) "And he shall reckon with his buyer" — with exactitude.

4) (Vayikra 25:50) ("And he shall reckon with his buyer from the year that he was sold to him until the Yovel year. And the money of his selling shall be according to the number of years. According to the days of a hired man shall he be with him.") "And he shall reckon with his buyer": and not with the heirs (of his buyer). "from the year that he was sold until the Yovel year": He does not go out in the sixth year. "And the money of his selling shall be according to the number of years. According to the days of a hired man shall he be with him.": He is acquired with money, and not with grain or vessels.

When Ezra came up (with) Zerubbabel, son of Shealtiel, and Jeshua, || son of Jehozadak, they began to build the Temple of the Lord, as it is said, "Then rose up Zerubbabel, the son of Shealtiel, and Jeshua, the son of Jozadak, and began to build the house of God" (Ezra 5:2). And the Samaritans came against them to fight (with) 180,000 (men). Were they Samaritans? Were they not Cutheans? But they were called Samaritans because of the city of Samaria. And further, they sought to kill Nehemiah, as it is said, "Come, let us meet together in one of the villages,… but they thought to do me mischief" (Neh. 6:2). Moreover, they made the work of the Lord to cease for two years ["Then ceased the work of the house of God, which is at Jerusalem]; and it ceased unto the second year of the reign of Darius, king of Persia" (Ezra 4:24).
