1 Corinthians 14:6-9

Geneva(i) 6 And nowe, brethren, if I come vnto you speaking diuers tongues, what shall I profite you, except I speake to you, either by reuelation, or by knowledge, or by prophecying, or by doctrine? 7 Moreouer things without life which giue a sounde, whether it be a pipe or an harpe, except they make a distinction in the soundes, how shall it be knowen what is piped or harped? 8 And also if the trumpet giue an vncertaine sound, who shall prepare himselfe to battell? 9 So likewise you, by the tongue, except yee vtter wordes that haue signification, howe shall it be vnderstand what is spoken? for ye shall speake in the ayre.
