Mark 4:9; Mark 4:23; Mark 7:16; Mark 7:33; Mark 8:18

9 And he said unto them, He that hath ears to hear , let him hear .
23 If any man have ears to hear , let him hear .
16 If any man have ears to hear , let him hear .
33 And he took him aside from the multitude, and put his fingers into his ears, and he spit , and touched his tongue;
18 Having eyes, see ye not? and having ears, hear ye not? and do ye not remember ?
