'Willing' in the Bible

So both of them sat down and ate and drank together; and the girl’s father said to the man, “Please be willing to spend the night, and let your heart be merry.”

But the man was not willing to spend the night, so he arose and departed and came to a place opposite Jebus (that is, Jerusalem). And there were with him a pair of saddled donkeys; his concubine also was with him.
