'Evening' in the Bible

They lamented and wept and fasted until evening because Saul, his son Jonathan, the Lord's people, and the house of Israel had fallen by the sword.

One evening David got up from his bed and walked around on the roof of his palace. From the roof he saw a woman bathing. Now this woman was very attractive.

Then David summoned him. He ate and drank with him, and got him drunk. But in the evening he went out to sleep on his bed with the servants of his lord; he did not go down to his own house.
