KJV ¹⁹ Then came the disciples to Jesus apart, and said, Why could not we cast him out?

TR1550 ¹⁹ τότε προσελθόντες οἱ μαθηταὶ τῷ ἰησοῦ κατ᾽ ἰδίαν εἶπον διατί ἡμεῖς οὐκ ἠδυνήθημεν ἐκβαλεῖν αὐτό

KJV ²⁰ And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

TR1550 ²⁰ ὁ δὲ ἰησοῦς εἶπεν αὐτοῖς διὰ τὴν ἀπιστίαν ὑμῶν ἀμὴν γὰρ λέγω ὑμῖν ἐὰν ἔχητε πίστιν ὡς κόκκον σινάπεως ἐρεῖτε τῷ ὄρει τούτῳ μετάβηθι ἔντεῦθεν ἐκεῖ καὶ μεταβήσεται καὶ οὐδὲν ἀδυνατήσει ὑμῖν
