Leviticus 19
33 “‘When a foreigner resides among you in your land, do not mistreat them. 34 The foreigner residing among you must be treated as your native-born. Love them as yourself, for you were foreigners in Egypt. I am the Lord your God. 35 “‘Do not use dishonest standards when measuring length, weight or quantity. 36 Use honest scales and honest weights, an honest ephah and an honest hin. I am the Lord your God, who brought you out of Egypt. 37 “‘Keep all my decrees and all my laws and follow them. I am the Lord.`”
