'Security' in the Bible

"A person sins against the LORD by acting treacherously toward his neighbor regarding something entrusted to his care, regarding security for a loan, robbery, if he has oppressed his neighbor,

If that person has sinned and has been found guilty, then he is to return the stolen thing that he took or obtained by oppression, or the security that had been entrusted to him, or the lost thing that he had found,
