Matt 20 16 KJV
“So the last shall be first, and the first last: for many be called, but few chosen.”

Read the parable given before this verse: about the land owner and his vineyard who hires different workers throughout the day but when the day is over gives each the same pay of a penny. The last were paid first and the first hired paid last but all received the same pay.

8So when even was come, the lord of the vineyard saith unto his steward, Call the labourers, and give them their hire, beginning from the last unto the first.
9And when they came that were hired about the eleventh hour, they received every man a penny.
10But when the first came, they supposed that they should have received more; and they likewise received every man a penny.
11And when they had received it, they murmured against the goodman of the house,
12Saying, These last have wrought but one hour, and thou hast made them equal unto us, which have borne the burden and heat of the day.
13But he answered one of them, and said, Friend, I do thee no wrong: didst not thou agree with me for a penny?
14Take that thine is, and go thy way: I will give unto this last, even as unto thee.
15Is it not lawful for me to do what I will with mine own? Is thine eye evil, because I am good?
16So the last shall be first, and the first last: for many be called, but few chosen.
