Matthew 17:19-21 Then the disciples having come to Jesus apart, said, Why could not we cast it out?

JuliaSmith⁽ⁱ⁾ ¹⁹ Then the disciples having come to Jesus apart, said, Why could not we cast it out? ²⁰ And Jesus said to them, For your unbelief: for truly I say to you, If ye have faith as a kernel of mustard, ye shall say to this mount, Go away from thence, and it shall go away; and nothing shall be impossible to you. ²¹ But this kind goes not forth but by prayer and fasting.
