One who became liable to two forms of execution is subjected to the more severe [form]. [If] he committed a transgression which was punishable by two [forms] of execution, he is subjected to the more severe [one]. R’ Yose says: He is subjected to the one by which he was first enjoined.

Someone who was flogged twice is placed by the court in a cell where he is fed barley until his stomach bursts. Someone who murders without witnesses [to that effect] is placed in a cell where he is fed spare bread and scant water.
