No unauthorized person may eat anything holy. No foreign guest of a priest or hired worker may eat anything holy. But if a priest should purchase someone with his own money, that person may share in eating it. Slaves born in his house may also share in eating his food.
~Leviticus 22:10,11

This text implies that circumcised foreigners who had been bought as laborers were thereafter considered to make up part of the priest’s household.

The priest’s immediate family members could also partake in holy meals.

Daughters were considered a part of the household if they were single, divorced or widowed and did not have children who could care for their needs (Lev. 22:13).

Jehovah truly extends his kindness toward every person regardless of their origin (Matt. 5:45).

From these verses we can gather at least a couple lessons:

1. God has his own arrangements as to who can enjoy things that he considers to be His own and how those things are enjoyed.

When we respect those arrangements, we are demonstrating godly devotion, especially if that implies making certain personal sacrifices (1 Tim. 6:6).

2. God is not partial toward any “but in every nation the man who fears him and does what is right is acceptable to him,” (Acts 10:34,35).

Therefor we should make a genuine effort to eradicate racist or prejudice notions that may have been engrained in us as children and that keep us from extending our hospitality toward members of our own faith who come from different roots.
