Mother's Day Central has some history of Mother's Days, from ancient to the modern.
Proverbs 31:10-11, 27-31 Who can find a virtuous woman? for her price is far above rubies. The heart of her husband doth safely trust in her...She looketh well to the ways of her household, and eateth not the bread of idleness. Her children arise up, and call her blessed; her husband also, and he praiseth her. Many daughters have done virtuously, but thou excellest them all. Favour is deceitful, and beauty is vain: but a woman that feareth the LORD, she shall be praised. Give her of the fruit of her hands; and let her own works praise her in the gates.
