Now viewing scripture range from the book of 1 Corinthians chapter 14:18
through chapter 14:21...
18 I thank my God, I speak with tongues more than ye all:
19 Yet in the church I had rather speak five words with my understanding, that [by my voice] I might teach others also, than ten thousand words in an [unknown] tongue.
20 Brethren, be not children in understanding: howbeit in malice be ye children, but in understanding be men.
21 In the law it is written, With [men of] other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord.
