Proverbs 31: 10-31 is a passage in the Old Testament written by King Lemuel's mother around the 10th Century B.C.. The passages were written as poetry to the King as advice on how to find a Godly wife and a "woman of valor". The whole idea of the passage is to describe "the perfect woman" and someone who would be fit to rule alongside a king as a strong and Godly woman. 

Becoming a Proverbs 31 Woman does not mean you have to be married or have kids. There are verses that mention how to be a good mother and wife, but preparing your heart for those things can help bring you closer to God. Working on becoming a Proverbs 31 woman is something that should be practiced daily, no matter where you are in your walk with God or in life.
