Moulton and Milligan – Vocabulary of the Greek NT is a Greek lexicon focusing on the Papyrus Greek.
A classic Greek lexicon useful for every theology student. Note that Thayer was a universalist, so be careful with any word dealing with salvation, and also the Trinity (his definition of “Christ” would seem to doubt Jesus’ deity). Basically the majority of his word definitions are from standard usage in the Greek NT and classical literature, so in theologically charged words, be careful.
