Deuteronomy 23:2 "When you come (to work) in your neighbor's vineyard, you may eat the grapes...you may Pluck the ears"

Mr. Lane is a farmer.

He has many workers reaping his harvest for him.

He pays them their wages regularly and on the first day that they begin work he tells them:

"Let's be fair to each other. When you are working in the vineyards, you may eat as many grapes as you like. But don't put any in a container to take home. When you work in the fields, you may nibble on some of the grain. But don't cut down any grain for yourselves to take with you."

With these instructions, Mr. Lane is fulfilling this Positive Mitzvah. It commands us to permit our workers to eat of the produce they are harvesting (see Negative Mitzvot 267-268).
