It is said that Moses took 40 years to travel from Egypt through the desert to the Promised Land. Considering the distance involved this must have been incompetence to the highest degree … perhaps he was going round in circles.
I reckon that unbeknown to him, Mrs Moses was asking for directions secretly and, when appropriate, she pointed him in the right way to go.
Being a woman, she allowed him to take all the credit for getting there at last.
Moral of the story:
Never rely on what you think you know. Always consider the possibility that you may be wrong. (Especially if your wife tells you so).
