if a man is lucky his wife is help, if not, a hindrance
If a man is blessed because his wife is a helper for his life, but if she is not blessed because she acts as his adversary (the original source of the expression is in the verse in Genesis 2:18: "And the Lord God said, It is not good that the man should be alone; I will make him a helper, as his adversary").
("It is not good for a man to be alone (Genesis 2) - hence the sages said: "He who is a servant without a wife is a servant without a good: I will make him a helper as his opposite. For a woman who helps a man, who brings wheat to grind and bake, and brings flax and spins and makes his clothes and clothes him and makes him stand on his feet, is a helper, not a helper as his opposite." - Midrash Agada (Buber) at the beginning of Chapter 2, and it says: "Rabbi Akiva taught: A man and a woman, merited the Shekinah between them, did not merit the fire of the slain" - Sota 17 a"a, and it says: "And it is known that a man's service and his service to the Lord are more than the one who follows the advice of his wife, and if she merited a helper, she did not merit an opponent" - Pela Yo'etz/ Ot 7, Zivug, and it says: "And it was "The helper, as opposed to him, spread out her hands in trade" - Agnon/ Elo and Elo)
