Matt 20:1 "For the kingdom of heaven is like a landowner who went out early in the morning to hire laborers for his vineyard.
2 Now when he had agreed with the laborers for a denarius a day, he sent them into his vineyard.
3 And he went out about the third hour and saw others standing idle in the marketplace,
4 and said to them, 'You also go into the vineyard, and whatever is right I will give you.' So they went.
5 Again he went out about the sixth and the ninth hour, and did likewise.
6 And about the eleventh hour he went out and found others standing idle, and said to them, 'Why have you been standing here idle all day?'
7 They said to him, 'Because no one hired us.' He said to them, 'You also go into the vineyard, and whatever is right you will receive.'
8 So when evening had come, the owner of the vineyard said to his steward, 'Call the laborers and give them their wages, beginning with the last to the first.'
9 And when those came who were hired about the eleventh hour, they each received a denarius.
10 But when the first came, they supposed that they would receive more; and they likewise received each a denarius.
11 And when they had received it, they complained against the landowner,
12 saying, 'These last men have worked only one hour, and you made them equal to us who have borne the burden and the heat of the day.'
13 But he answered one of them and said, 'Friend, I am doing you no wrong. Did you not agree with me for a denarius?
14 Take what is yours and go your way. I wish to give to this last man the same as to you.
15 Is it not lawful for me to do what I wish with my own things? Or is your eye evil because I am good?'
16 So the last will be first, and the first last. For many are called, but few chosen." [NKJV]
Young's Literal translates verse one in this manner:
1 `For the reign of the heavens is like to a man, a householder, who went forth with the morning to hire workmen for his vineyard,
So, the men are being chosen to do a job - a job in the Kingdom of Heaven, or "the reign of the heavens".
1 And Jesus answered and spoke to them again by parables and said:
2 "The kingdom of heaven is like a certain king who arranged a marriage for his son,
3 and sent out his servants to call those who were invited to the wedding; and they were not willing to come.
4 Again, he sent out other servants, saying, 'Tell those who are invited, "See, I have prepared my dinner; my oxen and fatted cattle are killed, and all things are ready. Come to the wedding." '
5 But they made light of it and went their ways, one to his own farm, another to his business.
6 And the rest seized his servants, treated them spitefully, and killed them.
7 But when the king heard about it, he was furious. And he sent out his armies, destroyed those murderers, and burned up their city.
8 Then he said to his servants, 'The wedding is ready, but those who were invited were not worthy.
9 Therefore go into the highways, and as many as you find, invite to the wedding.'
10 So those servants went out into the highways and gathered together all whom they found, both bad and good. And the wedding hall was filled with guests.
11 But when the king came in to see the guests, he saw a man there who did not have on a wedding garment.
12 So he said to him, 'Friend, how did you come in here without a wedding garment?' And he was speechless.
13 Then the king said to the servants, 'Bind him hand and foot, take him away, and cast him into outer darkness; there will be weeping and gnashing of teeth.'
14 For many are called, but few are chosen." [NKJV]
verse 2 in YLT: `The reign of the heavens was likened to a man, a king, who made marriage-feasts for his son,
Jesus is speaking to the Jews here, the Israelite nation which had been called to be a CHOSEN nation, called to be a blessing to all nations, called to reign in the heavens. They were the first guests to be invited to the Wedding of the Bridegroom, but they wanted nothing to do with it. And so their place at the wedding was given to others. Compare this to Romans 9-11 ~ do you see a connection?
Many are called to take part in the "reign of the heavens", the work of the Kingdom of Heaven, but few are actually chosen to do so and will respond to the call. This is my understanding.
