Know/Knew

The first seven books of the New Testament (and only those) infrequently contain the word:

know [Gr. gin(o)sk(o) and pronounced geen-OH-skoh]

The first four books of the New Testament (and only those) infrequently contain the word:

knew [Gr. egin(o)sken and pronounced egg-ee-NOHS-sken]

Exact references pertaining to "know" are:

Luke 1:34 (referring to Mary telling the angel that she knows not a man)
John 10:14 (referring to Jesus saying that He knows his sheep)
John 10:15 (referring to Jesus saying that He knows the Father)
John 10:27 (referring to Jesus saying that He knows his sheep) Acts 19:15 (referring to an evil spirit telling the seven sons of Sceva that he knows Jesus and comprehends Paul)
Romans 7:15 (referring to Paul telling us that he knows not what he does)
I Corinthians 13:12 (referring to Paul telling us that he knows in part but will fully know as he was fully known)

Exact references pertaining to "knew" are:

Matthew 1:25 (stating that Joseph knew not his wife Mary until she birthed her firstborn son)
Mark 15:10 (stating that Jesus knew that the chief priest had him arrested for envy)
Luke 7:39 (referring to a pharisee telling himself that Jesus should have known who and what the woman was who touched Him)
John 2:25 (stating that Jesus knew what was in man)

Scripture Text (in at least the English translations presently and commonly available) is not explicit nor does it elaborate about either of the Greek words "know" and "knew" mentioned above.
Certainly, the statement of Joseph "not knowing his wife" Mary in Matthew 1:25 has a sexual connotation relating to coital intercourse [being that obviously he would recognize her for identification in differentiating her apart from other people], as does Mary telling the angel she "does not know a man" in Luke 1:34 [in contrast to mere acquaintance recognition].
The other references containing the exact same Greek words with the exact same Greek letters makes the English-rendered words "know" and "knew" have a general meaning of mere conscious awareness and perception rather than exclusively an erotic connotation.

The word for [carnally] "knowing" someone in Hebrew-lettered wording is equivalent to Strong's Word# 3045. A sensuous application of that word is left to the imagination.
