If a man had pledged his slave as security and then set him free, the law declared that the slave is not liable for anything, but as a precaution the new master is compelled to give him a bill of emancipation, and the slave executes a bill of indebtedness for his value. Rabban Gamaliel says: He executes no document whatsoever. The one that set him free is liable. If a man is half slave and half free, he works one day for his master and one day for himself. This is according to the House of Hillel, but the House of Shamai said to them: This is well for the master, but not so for the man. He may not marry a slave, since he is half free, and he can not marry a free woman because he is half slave. Shall he remain unmarried forever? Was not the world made for fruition and increase? As was said: (Isaiah xlv, 18) He created it not in vain, he formed it to be inhabited. For the general good, the master is compelled to set the half slave free, and the man gives him a pledge for a half of his value. The House of Hillel changed their view and taught according to the decision of the House of Shamai.
If a man sold his slave to a foreigner or beyond the borders of the Land of Israel, the slave must be set free.

Fear must not motivate a decision.
