"There are many others to whom we might make our homes a blessing. Our social entertainments should not be governed by the dictates of worldly custom, but by the Spirit of Christ and the teaching of His word. The Israelites, in all their festivities, included the poor, the stranger, and the Levite, who was both the assistant of the priest in the sanctuary, and a religious teacher and missionary. These were regarded as the guests of the people, to share their hospitality on all occasions of social and religious rejoicing, and to be tenderly cared for in sickness or in need. It is such as these whom we should make welcome to our homes. How much such a welcome might do to cheer and encourage the missionary nurse or the teacher, the care-burdened, hard-working mother, or the feeble and aged, so often without a home, and struggling with poverty and many discouragements. MH 352.4"
"And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the Lord your God."
Both passages emphasize the importance of including the less fortunate (poor, stranger, Levite/missionary, etc.) in social gatherings and providing for their needs. EGW expands on the principle found in Leviticus, applying it to contemporary situations.
