'Hearken' in the Bible

And it came to pass on the seventh day, that the child died. And the servants of David feared to tell him that the child was dead: for they said, Behold, while the child was yet alive, we spake unto him, and he would not hearken unto our voice: how will he then vex himself, if we tell him that the child is dead?

Howbeit he would not hearken unto her voice: but, being stronger than she, forced her, and lay with her.

And she said unto him, There is no cause: this evil in sending me away is greater than the other that thou didst unto me. But he would not hearken unto her.
