John Gill Commentary Job 32:16

"And shall I wait, because they speak not, Because they stand still, and answer no more?" — Job 32:16 (ASV)

When one had waited
To observe whether they would make any reply to what he had said, or any objection to his engaging in the controversy:

for they spoke not ;
were as mute as fishes:

but stood still ;
like statues, had no power to move, neither to sit down nor to depart, but were as if all life, sense, and motion, were gone from them:

[and] answered no more ;
or not at all; for it does not appear that they had given him any answer before, as well as not now.
