Mark 9:20

9:20 So they brought the boy ¹  to him. When the spirit saw him, it immediately threw the boy into a convulsion. He ²  fell on the ground and rolled around, foaming at the mouth.

Mark 9:18

9:18 Whenever it seizes him, it throws him down, and he foams at the mouth, grinds his teeth, and becomes rigid. I asked your disciples to cast it out, but ³  they were not able to do so.” ⁴ 

¹ tn Grk “him.”

² tn Because of the length and complexity of the Greek sentence, a new sentence was started here in the translation.

³ tn Here καί (kai) has been translated as “but” to indicate the contrast present in this context.

⁴ tn The words “to do so” are not in the Greek text, but have been supplied for clarity and stylistic reasons.
