1 Corinthians 14:7

And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?

Cross-reference

In 1 Corinthians 14:8, Paul extends the analogy to a trumpet: without clear call, no battle readiness—same point as 14:7 about distinct notes.

In 1 Corinthians 13:1, Paul compares tongues without love to clanging cymbal, same musical instrument analogy as 14:7's flute/harp for meaningless noise.

In Numbers 10:2-10, silver trumpets signaled distinct assemblies and battles—background for Paul's trumpet analogy in 14:8 about clear communication.
