KJV:
And they come unto thee as the people cometh, and they sit before thee as my people, and they hear thy words, but they will not do them: for with their mouth they shew much love, but their heart goeth after their covetousness.
NASB:
"They come to you as people come, and sit before you as My people and hear your words, but they do not do them, for they do the lustful desires expressed by their mouth, and their heart goes after their gain.
KJV:
And, lo, thou art unto them as a very lovely song of one that hath a pleasant voice, and can play well on an instrument: for they hear thy words, but they do them not.
NASB:
"Behold, you are to them like a sensual song by one who has a beautiful voice and plays well on an instrument; for they hear your words but they do not practice them.
