In 1 Corinthians 13:1, what does Paul say he is like if he speaks without love?

Answer: A clanging cymbal

Speaking in the tongues of men and angels without love, Paul is only a ringing gong (KJV: sounding brass) or a clanging cymbal.

“If I speak in the tongues of men and of angels, but have not love, I am only a ringing gong or a clanging cymbal.”— 1 Corinthians 13:1 (BSB)
