“Wherefore let him that speaketh in an unknown tongue pray that he may interpret.”
King James Version (KJV)
14:13 That he may be able to interpret - Which was a distinct gift.
1Co 14:13 Let him that speaketh in an [unknown] language pray that he may interpret. Let him pray that he may have the gift of interpretation also. See PNT "1Co 12:10". Let him pray that he may understand what he utters, so as to explain it.
