Matthew 17:19

Then came the disciples to Jesus apart, and said, Why could not we cast him out?

Then the disciples came to Jesus privately, and said, "Why weren't we able to cast it out?"

Then came the disciples to Jesus apart, and said, Why could not we cast it out?

Then the disciples having come to Jesus by himself, said, `Wherefore were we not able to cast him out?'

Afterward the disciples came to Jesus privately and asked, “Why couldn’t we drive it out?”
