1 Corinthians 14:19

howbeit in the church. had rather speak five words with my understanding, that. might instruct others also, than ten thousand words in. tongue.

'howbeit in the church' -'in the assembly' (Alf). Again, 'the public assembly of the congregation for worship' is the context of this chapter. In such. setting, where everyone spoke the same language, uninterpreted foreign languages were unprofitable.

'five words with my understanding' -'five words that can be understood.' (Beck); 'five intelligible words' (NEB)

'that. might instruct others' -the implication being that they should wish to do the same. 'All things are lawful, but not all things are profitable.. (1 Corinthians 10:23)

'ten thousand' -'the largest word for numbers available in Greek.' (Fee p. 675)
