Leviticus 19:10

And thou shalt not go over the gathering of thy vineyard, neither shalt thou gather the remaining grapes of thy vineyard: thou shalt leave them for the poor and the stranger: I am the Lord your God.

And thou shalt not glean thy vineyard, neither shalt thou gather every grape of thy vineyard; thou shalt leave them for the poor and stranger: I am the Lord your God.

You shall not glean your vineyard, neither shall you gather the fallen grapes of your vineyard. You shall leave them for the poor and for the foreigner. I am Yahweh your God.
