KJV: Moreover when ye fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear unto men to fast. Verily I say unto you, They have their reward.
NASB: "Whenever you fast, do not put on a gloomy face as the hypocrites do, for they neglect their appearance so that they will be noticed by men when they are fasting. Truly I say to you, they have their reward in full.
KJV: Behold, ye despisers, and wonder, and perish: for I work a work in your days, a work which ye shall in no wise believe, though a man declare it unto you.
NASB: 'BEHOLD, YOU SCOFFERS, AND MARVEL, AND PERISH; FOR I AM ACCOMPLISHING A WORK IN YOUR DAYS, A WORK WHICH YOU WILL NEVER BELIEVE, THOUGH SOMEONE SHOULD DESCRIBE IT TO YOU.'"
KJV: Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
NASB: Yet you do not know what your life will be like tomorrow. You are just a vapor that appears for a little while and then vanishes away.
