'Evening' in the Bible

And it came to pass at evening time that David arose from off his couch, and walked upon the roof of the king's house; and from the roof he saw a woman bathing, and the woman was very beautiful;

And David invited him, and he ate and drank before him; and he made him drunk. And in the evening he went out to lie on his couch with the servants of his lord, but did not go down to his house.
