'Listening' in the Bible

And he said, I will certainly return to thee at this time of the year, and behold, Sarah thy wife shall have a son. And Sarah was listening at the tent-door, which was behind him.

And he came near to her; and the woman said, Art thou Joab? And he said, I am he. And she said to him, Listen to the words of thy handmaid. And he said, I am listening.
