Saul sent messengers to David's house, to watch him, and to kill him in the morning: and Michal, David's wife, told him, saying, If you don't save your life tonight, tomorrow you will be slain.
Saul's evil influence upon members of his own family is seen in the readiness with which Michal lied to her father, and also her possession of some kind of an idol with the implication that she probably worshipped it. The "teraphim" (the RSV margin) is a plural form with a singular sense, usually meaning household gods."[12]  This must have been a secret which she kept from David.  Nevertheless, one cannot help admiring the noble and courageous action she exhibited in saving her husband's life.
