13 Therefore let him who speaks in a tongue pray that he may interpret.
13 For this reason the one who speaks in a tongue should pray that they may interpret what they say.
13 Wherefore let him that speaketh in an unknown tongue pray that he may interpret.
13 So, when you pray in your private prayer language, don't hoard the experience for yourself. Pray for the insight and ability to bring others into that intimacy.
