Kiddushin 18 - Master or his Son to Marry Hebrew Maidservant
A Hebrew convert is like a new-born child and does not inherit his father, except by rabbinical ordinance. He has to tell his brothers, "Take these idols, and I will take the produce," before the idols come into his possession.
A father can sell his daughter into servitude only once. Her master or master's son are expected to marry her and provide for her, with no additional Kiddushin money required.
A Hebrew servant is sold for his theft if he can not repay, but only if what he owes exceeds the value of the six years of his servitude.
