In depth
From the study of Hebrews 11:8
- Range of meaning
To know, understand, be acquainted with, know how to do something.
- Against the English
'Not knowing where' is accurate. The point is that he did not know the destination. It does not mean he was unsure about God.
- Used elsewhere in the period
This matches Genesis 12:1, 'to the land that I will show you,' where the land is not named. Philo dwells on the same detail (On the Migration of Abraham 43–44).
- Range of meaning
To know or understand, often with a sense of competence or being well informed ("know how," "be versed in"). It can also simply mean "be aware of a fact."
- Against the English
All versions have "know," which is correct. Some of the word's feel of informed expertise is lost.
- Used elsewhere in the period
Used of the knowledge of a craft or skill in classical Greek. In the New Testament it is common in Acts (e.g., 10:28; 19:15; 20:18) for well-grounded knowledge. James uses it only here.
- Range of meaning
To understand, know how, be acquainted with, know about or be aware of a fact or person. In classical Greek it often means skilled or expert knowledge. In Koine it is commonly just "know (that)" or "be acquainted with" (BDAG; LSJ).
- Against the English
YLT "I am acquainted with", NIV "I know about" and BSB "I know about" bring out the difference from ginōskō. ESV and NASB keep the change by moving "recognize" around ("Paul I recognize" / "I recognize Jesus"). KJV, WEB and NLT render both verbs simply as "know".
- Used elsewhere in the period
Luke uses this verb more than any other New Testament writer: Acts 10:28; 15:7; 18:25; 19:25; 20:18; 22:19; 24:10; 26:26. In nearly every case it means knowing facts ("you know that…"). Luke likes the word, which is a reason for caution about making too much of the contrast here.

But one day the evil spirit responded, “Jesus I know, and I know about Paul, but who are you?”

he is conceited and understands nothing. Instead, he has an unhealthy interest in controversies and disputes about words, out of which come envy, strife, abusive talk, evil suspicions,
Here: "Understanding." This is the knowledge of someone who really grasps a subject. It is ironic, because these teachers claim special knowledge (compare 6:20, "what is falsely called knowledge").
