Does the Bible permit women to be prophets?

Yes, and the text doesn't treat it as remarkable. The Hebrew word for prophetess (nebiah) is used six times in the Old Testament — five times for genuine prophetesses introduced without apology — and Peter at Pentecost cites Joel 2 as the scriptural ground for women prophesying in the last days.

Yes — and the striking thing is how little fanfare the Bible makes about it. The Hebrew language has a specific word for "prophetess," nebiah (נְבִיאָה, H5031), the feminine form of nabi (prophet). It appears six times in the Old Testament, and five of those six times it names a genuine prophetess without any apologetic framing.

The five are Miriam (Exodus 15:20), Deborah (Judges 4:4), Huldah (2 Kings 22:14 and 2 Chronicles 34:22), Isaiah's wife (Isaiah 8:3), and — in the New Testament — Anna in the temple (Luke 2:36). The sixth, Noadiah (Nehemiah 6:14), is condemned — but notice why. She is grouped with "the rest of the prophets" who were trying to intimidate Nehemiah. The charge is intimidation, not female speech. The canon condemns false prophecy on content-and-source grounds whether the prophet is male or female.

In every positive case, the narrator simply names the woman and keeps moving:

"Then Miriam the prophetess, the sister of Aaron, took a tambourine in her hand." — Exodus 15:20

"Now Deborah, a prophetess, the wife of Lappidoth, was judging Israel at that time." — Judges 4:4

No "despite being a woman." No "because there was no man available." The text simply says she was one.

And when the New Testament opens its account of the new covenant, the Spirit's fulfillment of Joel 2 is named publicly and explicitly. Peter stands up at Pentecost and quotes:

"And your sons and your daughters shall prophesy ... even on my male servants and on my female servants in those days I will pour out my Spirit, and they shall prophesy." — Acts 2:17–18

The verb propheteusousin (προφητεύσουσιν, G4395, "they will prophesy") applies to sons and daughters alike. Peter introduces the quotation with "this is what was spoken through the prophet Joel" — direct identification, not analogy. The last days, Peter says, are the days when daughters prophesy. Luke confirms it was already happening by reporting, almost in passing, that Philip the evangelist had "four unmarried daughters who were prophesying" (Acts 21:9).

The canon's answer is settled. The office exists. The Hebrew language has a word for it. Yahweh sends women as prophets (Micah 6:4 names Miriam alongside Moses and Aaron as sent by God), and the Spirit at Pentecost pours out prophecy on daughters as well as sons.
