A.T. Robertson Commentary Romans 10:18

"But I say, Did they not hear? Yea, verily, Their sound went out into all the earth, And their words unto the ends of the world." — Romans 10:18 (ASV)

Did they not hear? (μη ουκ ηκουσαν?). Rather, "Did they fail to hear?" (expecting the negative answer μη, while ουκ blends with the verb). See on 1 Corinthians 9:5 for this construction.

Yea, verily (μενουνγε). Triple particle (μεν, ουν, γε) as in 9:20.Sound (φθογγος). Vibration of a musical string. See on 1 Corinthians 14:7. Only two N.T. examples.

The world (της οικουμενης). The inhabited earth as in Lu 2:1.
