Charles Spurgeon Commentary Matthew 20:10-12

"And when the first came, they supposed that they would receive more; and they likewise received every man a shilling. And when they received it, they murmured against the householder, saying, These last have spent [but] one hour, and thou hast made them equal unto us, who have borne the burden of the day and the scorching heat." — Matthew 20:10-12 (ASV)

But when the first came, they supposed that they should have received more; and they likewise received every man a penny.
