And when they had come to the multitude, there came to him a certain man kneeling down to him, and saying,

What think ye? If a certain man should have a hundred sheep, and one of them be gone astray, does he not, leaving the ninety and nine on the mountains, go and seek the one that has gone astray?

But look! a certain man came up to him and asked, "Teacher, what good thing shall I do to inherit eternal life?"

But what think ye? A certain man had two sons; and he came to the first, and said, Son, go, work to-day in my vineyard.

'Hear ye another simile: There was a certain man, a householder, who planted a vineyard, and did put a hedge round it, and digged in it a wine-press, and built a tower, and gave it out to husbandmen, and went abroad.

"Likewise, as a certain man, ready to take his journey to a strange country, called his servants to him, and delivered to them his goods.

He said, “Go into the city to a certain man, and say to him, ‘The Teacher says, “My time [to suffer and atone for sin] is near; I am to keep the Passover at your house with My disciples.”’”
