Leviticus 19:3-4, 10, 34

Every one of you shall revere his mother and his father, and you shall keep my Sabbaths: I am the LORD your God. Do not turn to idols or make for yourselves any gods of cast metal: I am the LORD your God.

And you shall not strip your vineyard bare, neither shall you gather the fallen grapes of your vineyard. You shall leave them for the poor and for the sojourner: I am the LORD your God.

You shall treat the stranger who sojourns with you as the native among you, and you shall love him as yourself, for you were strangers in the land of Egypt: I am the LORD your God.
