Pr 31:15 She riseth also while it is yet night, and giveth meat to her household, and a portion to her maidens.
Some believe that in order to be virtuous, we need to be up before dawn. I believe some are called by the Lord to do this, while others aren't. Sometimes we are called to be up that early for a season of our lives. But I believe you can be virtuous and sleep in till 7 or 8. I think the important thing is what we do after we are up. It is easier when there are little children in the home to rise early before them and spend time with the Lord.
Also the last part of the verse says she gives a portion of the food she makes for her family in the morning to her maidens. These were her servants. Some may wonder wy they didn't get up and make food for her and her family while she slept in til later. I think it proves her virtue that she would come alongside or ahead of them and do some of the work she easily could have required them to do for her.
We always had our children help around the house. But rarely were they working alone. I was usually working along side or doing something near by. We did it together. It helped them to do it with a good attitude when they knew I was not wasting my time and neither should they. And it went quickly since we were all in it together. Also I was there to supervise and make sure the job was done correctly, or to instruct how it needed to be done. No surprises later on when they were off doing something fun, and I checked and something wasn't done or not done correctly.
All four of our children have always been complimented by their bosses on the job they do. We are always told how they can be taught what needs to be done and left to do the job. Their boss knows when they come back later it will be done and done correctly. They were taught at an early age to do it that way and now as adults they have great work ethics and habits.
