Idioms & expressions
assure oneself of something

"Before proceeding, he assured himself of the accuracy of the data."
From Old French 'assurer', from 'asseurer' (to make sure, secure), ultimately from Latin 'ad-' (to) + 'securare' (to make safe).
Historically, 'assure' held a stronger connotation of making something safe or secure, a nuance that is less prominent in modern usage.
