Lamsa(i)
12 Likewise you, since you are zealous of spiritual gifts for the edification of the church, seek that you may excel in these gifts.
13 Thus he who speaks in an unknown tongue, pray that he may interpret it.
14 For if I pray in an unknown tongue, my spirit prays, but my knowledge is fruitless.
15 What then shall I do? I will pray with my spirit, and I will pray with my understanding also: I will sing with my spirit, and I will sing with my understanding also.
16 Otherwise, if you say a blessing with the spirit, how can one who occupies the place of the unlearned say Amen to your thanksgiving, since he does not understand what you say?
17 For indeed you bless well, but your fellow man is not enlightened.
