28.16 · Know · Know
to lack knowledge, to have no knowledge, ignorance the state of lacking knowledge For another interpretation of ἀγνωσία in 1CO 15:34, see 32.7. In 1PE 2:15, ἀγνωσία may involve lack of understanding (see 32.8).
1 1PE 2:15 The semantic structure of φιμοῦν τὴν τῶν ἀφρόνων ἀνθρώπων ἀγνωσίαν is extremely complex, since φιμοῦν ‘to silence’ would normally be related to ‘foolish people,’ and it is clearly these who are the ones talking about things ‘which they do not understand.’
