John Gill Commentary Luke 20:10

"And at the season he sent unto the husbandmen a servant, that they should give him of the fruit of the vineyard: but the husbandmen beat him, and sent him away empty." — Luke 20:10 (ASV)

And at the season
Or "when it the time of fruit", as the Ethiopic version renders it, agreeably to (See Gill on Matthew 21:34):

he sent a servant to the husbandmen ;
or servants, as in (Matthew 21:34) ; the prophets of the Lord, his messengers, whom he sent to them, to exhort them to bring forth the fruits of righteousness, as follows:

that they should give him of the fruit of the vineyard ;
that is, that they, bringing forth good fruit in their lives and conversations, whereby it might appear that they were trees of righteousness, and the planting of the Lord; he, or they observing them, might give an account of them to the Lord, to the glory of his name:

but the husbandmen beat him, and sent him away empty ;
the Jews not only mocked these messengers of the Lord, and despised their words, but misused them, (2 Chronicles 36:15 2 Chronicles 36:16) they beat them with their fists, smote them on the cheek, and scourged them with scourges; so that they had no account to give of their fruitfulness in good works, but the contrary; (See Gill on Matthew 21:35) and (See Gill on Mark 12:3).
