Paul the Apostle, if you speak in tongues, you need an interpreter! This actually belies a truth, if one does authentically speak in tongues, you may be unsure from who the tongues are speaking. Douay-Rheims, Corinthians 1:13 and 1: 28: 1 Corinthians 14 DRB (biblehub.com) 27If any speak with a tongue, let it be by two, or at the most by three, and in course, and let one interpret. 28But if there be no interpreter, let him hold his peace in the church, and speak to himself and to God. That's a rather interesting concept.
