"If authentic, this unqualified use of the verb seems to tell against the probability that only a single form of speech is prohibited. Elsewhere Paul has said 'speak in tongues' when that is in view, and when he means 'discern' he says 'discern', not 'speak'. Again, as with the opening 'rule', the plain sense of the sentence is an absolute prohibition of all speaking in the assembly". Fee, Gordon (1987).
