She makes coverings for her bed;
she is clothed in fine linen and purple.
In the Old Testament, the color purple was a sign of royalty, dignity, and respect. If someone was clothed in purple, people instantly new their place in society and they were to be treated with respect and honor. This woman clothed herself in the finest linens to reflect the finest parts of her Spirit. The term "fine linens" doesn't translate to "most expensive." It simply means, that her appearance was well taken care of and she was well respected because of the way she carried herself.
I'm so thankful that God doesn't consider our outward appearance, but He does repeatedly remind us throughout Scripture that our bodies are a temple and we are to glorify Christ with our bodies. Therefore, our outward appearance not only represents God but it represents our families as well. Proverbs 12 implies that a worthy wife is a crown to her husband.......its hard to be a what a crown represents, not only our husbands but to the Lord, when our bodies, hygiene, and appearance are not well taken care of.
Let me clarify again by saying that it doesn't imply we dress head to toe in the most expensive thing we have all the time, this Scripture is implying that we strive for excellence in everything, especially the first impression we allow people to perceive from us. We want people to respect us, because we are His.
