My take on Deuteronomy 22:11

"Thou shalt not wear a garment of ^adivers sorts, as of woollen and linen together."

Some Orthodox Jews still do this today. Apparently, there are people whose career is to examine the fibers of your clothes to make sure you are keeping this commandment.

Here's my personal interpretation of this law. In the time of Deuteronomy, people were much more connected to their clothing. They herded and shore the sheep, and gathered the cotton themselves. They spun the thread. They wove the thread. It was an important part of their lives. If they didn't do this, they wouldn't have clothes.

Lambs and sheep are often symbolic of Christ. The commandment to not mix wool with linen might have reference to the idea that you should not mix the divine with the secular. Perhaps it's a reminder to keep Christ and religious truths pure and separate from philosophies of the world.
