PROCTOR: I – I have once or twice plowed on Sunday. I have three children, sir, and until last year my land give little.
GILES: You’ll find other Christians that do plow on Sunday if the truth be known.
HALE: Your Honor, I cannot think you may judge the man on such evidence.

– Arthur Miller

The Crucible, Act 2. When Cheever attacks John Proctor for failing to observe the Bible teaching by working on the sabbath day, Proctor admits that he has "once or twice" plowed on Sunday because he had children to feed. Giles Corey and Reverend Hale come to John’s defense, suggesting that this doesn’t prove he isn’t a true Christian. This passage is an allusion to God’s teaching about the sabbath in the Book of Exodus: "Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work."
