German to English Bus/Financial Insurance

Hi,

The term in question appears in the first sentence (after Dear Sir/Madam) of a letter from the Federal Insurance Institution For Salaried Employees.


Sie beziehen von der Bundesversicherungsanstalt für Angestellte eine Leistung aus der gesetzlichen Rentenversicherung.


I would like to know what exactly is meant by 'beziehen' in this context.

Thank you very much for your time.

Regards,
