The Jews are mostly a secular nation.
If they followed their faith then God would help them. Here are a few passages from the Bible that say how the Jews should treat aliens, or foreigners living in Israel.
Leviticus 19
33 " 'When an alien lives with you in your land, do not mistreat him.
34 The alien living with you must be treated as one of your native-born. Love him as yourself, for you were aliens in Egypt. I am the LORD your God..
Ezekiel 47
21 “You are to distribute this land among yourselves according to the tribes of Israel. 22 You are to allot it as an inheritance for yourselves and for the foreigners residing among you and who have children. You are to consider them as native-born Israelites; along with you they are to be allotted an inheritance among the tribes of Israel. 23 In whatever tribe a foreigner resides, there you are to give them their inheritance,” declares the Sovereign LORD.
Leviticus 24
You are to have the same law for the alien and the native-born. I am the LORD your God.
Exodus 22:21
"Do not mistreat an
alien or oppress him, for you were
aliens in Egypt.
Leviticus 19:10
Do not go over your vineyard a second time or pick up the grapes that have fallen. Leave them for the poor and the
alien. I am the LORD your God.
