Deuteronomy 10:18-19 is today’s passage reflecting on God’s attitude towards foreigners.
He defends the cause of the fatherless and the widow, and loves the foreigner residing among you, giving them food and clothing. And you are to love those who are foreigners, for you yourselves were foreigners in Egypt.
These verses come from the section of the passage in chapter 10 about fearing the Lord. I would read this whole section in your Bible or from Bible Gateway here: http://www.biblegateway.com/passage/?search=Deuteronomy%2010&version=NIV
