Reading through the Bible together
From time to time throughout Deuteronomy we see Moses setting forth apparently insignificant details. But life is the composite of details. If God (through Moses) hadn’t dealt with these issues, the people would have resorted to adopting the practices either brought from Egypt by their grandparents or those from the surrounding countries. God wanted his people to be holy and still does. (1 Peter 1:15-16)
The Hebrew and Greek words for holiness convey the idea “to be set apart.” Set apart from what? The world of course. We are told that we are "in the world" (John 17:11) but that we are not to be "of the world" (John 17:16). Therefore it is no wonder that God is still interested in the little details of our lives. For sure, times have changed over the last 3000 years since Moses enumerated these details of living, and yet there are principles that can be adapted and applied to our day. We can and should be a “holy” people.
For instance: “Beautiful” female captives resulting from war could be kept and married. But they were not to be from the original inhabitants of the Promised Land. The rules show that female captives resulting from war were to be assimilated into society and treated with respect and dignity.
“Dear God, help me today to treat all people with respect and dignity, always allowing for them to freely express their individuality.”
