'Hearken' in the Bible

Let thine ear now be attentive, and thine eyes open, that thou mayest hearken unto the prayer of thy servant, which I pray before thee at this time, day and night, for the children of Israel thy servants while I confess the sins of the children of Israel, which we have sinned against thee. Yea, I and my father's house have sinned:

Shall we then hearken unto you to do all this great evil, to trespass against our God in marrying foreign women?
