Leviticus 19:32-36

‘You shall stand up in the presence of the grayheaded and honor elders, and you shall fear your God; I am the Lord.

‘When a stranger resides with you in your land, you shall not do him wrong.

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 strangers in the land of Egypt; I am the Lord your God.

‘You shall do no wrong in judgment, in measurement of weight, or volume.

You shall have accurate balances, accurate weights, an accurate ephah, and an accurate hin; I am the Lord your God, who brought you out from the land of Egypt.
