Leviticus 19:3-4, 10, 34

Every one of you shall reverence 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 molten gods; I am the LORD your God.

Nor shall you glean your vineyard, nor shall you gather the fallen fruit of your vineyard; you shall leave them for the needy and for the stranger. I am the LORD your God.

The stranger who resides with you shall be to you as the native among you, and you shall love him as yourself, for you were aliens in the land of Egypt; I am the LORD your God.
