She is also strong. The Hebrew word used here is "oz," which means "might" or "strength." It includes material or physical strength, but it goes beyond that as well. It also means "personal, social or political" strength.
Women are not these frail beings that patriarch society often portrays. Women are strong, perhaps not as physically dominant, but that does not mean they are weak. A fierce personal strength and intellect can overcome many strenuous tests. Women are able to stand on their own in the social and political scene. Unlike the patriarch traditions dictate, women have the competency to handle themselves. It is a flawed human society that puts women in a place behind man, not God.
The strength of a person, man or woman, is weak without God.
Ephesians 6:10 -- "A final word: Be strong in the Lord and in his mighty power."
Without God we can't really accomplish much. Our true strength comes from the one who created us. The wife of noble character knows, in her heart, that she inherits her strength from the Lord.
The wife of noble character is also a hard worker. She does her duties with joy and doesn't cease until the job is finished and done right.
Proverbs 12:11 -- "A hard worker has plenty of food, but a person who chases fantasies has no sense."
A hard worker provides for herself and her family. Laziness and procrastination are foolish. Integrity is the willingness to live by your beliefs and standards. The woman of noble character is energetic, strong and a hard worker. You can see the fruits of this labor throughout the scripture by how her character affects everyone and everything around her in a positive way. She is keeping her integrity and her noble character throughout ever facet of her life.
