ἀγνοέω
agnoéō · verb · “to be ignorant”
Agnoeō means to not know or be ignorant of something. Paul uses it to introduce truths he does not want believers to miss: “I do not want you to be ignorant.”
Agnoeō is the simple opposite of knowing. It can describe culpable ignorance — willful not-knowing — or simply the lack of information.
Paul’s favorite use is pastoral: “I do not want you to be ignorant (agnoein), brothers.” Romans, Corinthians, and Thessalonians each have moments where he stops to make sure believers grasp what matters — about Israel, the gifts, the dead in Christ, the return of Jesus.
Definition: not to know (through lack of information or intelligence); by implication, to ignore (through disinclination)
KJV usage: (be) ignorant(-ly), not know, not understand, unknown
