'Sleeping' in the Bible

How much more, when evil men have put an upright person to death, in his house, sleeping on his bed, will I take payment from you for his blood, and have you cut off from the earth?

And Uriah said to David, Israel and Judah with the ark are living in tents, and my lord Joab and the other servants of my lord are sleeping in the open field; and am I to go to my house and take food and drink, and go to bed with my wife? By the living Lord, and by the life of your soul, I will not do such a thing.
