'Intimate' in the Bible

Mary asked the angel, “How can this be, since I have not been intimate with a man?”

No one has seen God [His essence, His divine nature] at any time; the [One and] only begotten God [that is, the unique Son] who is in the intimate presence of the Father, He has explained Him [and interpreted and revealed the awesome wonder of the Father].

And on the morrow they came to Caesarea. But Cornelius was looking for them, having called together his kinsmen and his intimate friends.

For if I [or anyone else should] rebuild [through word or by practice] what I once tore down [the belief that observing the Law is essential for salvation], I prove myself to be a transgressor.

[I always pray] that the God of our Lord Jesus Christ, the Father of glory, may grant you a spirit of wisdom and of revelation [that gives you a deep and personal and intimate insight] into the true knowledge of Him [for we know the Father through the Son].
