1CO 9:10

10 Whether for us he saith these things? For why those be written for us; for he that eareth, oweth to ear in hope, and he that thresheth, in hope to take (some) fruits. (Whether he saith these things for us? Yea, they be written for us; for he that ploweth, ought to plow in hope, and he that reapeth, in hope to take some fruits.)
