Mateo 17

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

Entonces, llegándose los discípulos á Jesús, aparte, dijeron: ¿Por qué nosotros no lo pudimos echar fuera?

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?”
