Revelation 2:3, 13

and [I know that] you [who believe] are enduring patiently and are bearing up for My name’s sake, and that you have not grown weary [of being faithful to the truth].

‘I know where you dwell, [a place] where Satan sits enthroned. Yet you are holding fast to My name, and you did not deny My faith even in the days of Antipas, My witness, My faithful one, who was killed (martyred) among you, where Satan dwells.
