1 Corinthians 14:2-4

New Testament for Everyone

² Someone who speaks in a tongue, you see, isn’t speaking to human beings but to God. Nobody can understand such speakers, because they speak mysteries in the spirit. ³ But the one who prophesies speaks to other people, to build them up, to strengthen them, and to console them. ⁴ The one who speaks in a tongue builds up himself or herself; but the one who prophesies builds up the church.
