Charles Spurgeon Commentary Matthew 21:36

"Again, he sent other servants more than the first: and they did unto them in like manner." — Matthew 21:36 (ASV)

The lord of the vineyard was patient and gave them further opportunities to mend their ways. Again, he sent other servants. Failure to bring back the fruit was not the fault of the first messengers, for other servants were rejected even as they had been.

The householder was very anxious to win the tenant farmers to a better state of mind, for he increased the number of his representatives, sending more than the first, trusting that the evil men would yield to repeated calls. No good came of this effort of kindness, for the wicked tenant farmers only continued their murderous cruelty and did the same to them.

It was evidently a bad case. The Jewish people would not listen to the voices of the Lord’s servants, and their rulers set them the example of persecuting the men whom God had sent to them.
