How do we make these commandments work in daily life? Two ways: taking the past and make yourself an extension of it. Saying to yourself, “this is the way it was back then, and so this is how we do it now”. This is Orthodoxy. The other way is to make your values the same as the Hebrews, making the Hebrews feminist, vegan-anarchists or whatever you may be.
Here’s the problem: we live in a different world than the Hebrews. Our values, and their values are completely different. And it’s important to recognize and celebrate those differences. Sometimes they were right, and sometimes our modern values are superior to theirs.
Bottom line: be yourself. And by the way, if you read this week’s Torah portion literally, don’t take any “beautiful captives”. They call that “abduction” and “human trafficking” now.
