1 Corinthians 14:2-4 New International Version Anglicized (NIVUK)

2. For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit.

3. But the one who prophesies speaks to people for their strengthening, encouraging and comfort.

4. Anyone who speaks in a tongue edifies themselves, but the one who prophesies edifies the church.
