Therefore Michol the daughter of Saul had no child to the day of her death.

Therefore Michal the daughter of Saul had no child until the day of her death.

And Michal, Saul's daughter, had no child till the day of her death.

And so, there was no child born to Michal, the daughter of Saul, even to the day of her death.

Therefore Michal the daughter of Saul had (l) no child unto the day of her death.
(l) Which was a punishment because she mocked the servant of God.

Therefore Michal the daughter of Saul had no child until the day of her death. The children she brought up for Adriel were not her own, but adopted ones, or Adriel's by another woman, 2-Samuel 21:8; however, she had none after this time, whatever she had before, and it does not appear that she had any, though the Jews say she was Eglah, and Ithream her son; see Gill on 2-Samuel 3:5. And thus she that vilified David brought a reproach upon herself, as barrenness was always reckoned, and no one descending from her arrived to royal dignity, and sat on the throne of David; and so it was ordered in Providence, as Abarbinel observes, that the seed of David and of Saul might not be mixed.

Michael was humbled by God for her pride, and remained childless to the time of her death.

Therefore - Because of her proud and petulant speech and carriage to David, which God justly punished with barrenness. No child - After this time.
