and Absalom her brother saith unto her, 'Hath Amnon thy brother been with thee? and now, my sister, keep silent, he is thy brother; set not thy heart to this thing;' and Tamar dwelleth -- but desolate -- in the house of Absalom her brother.

and Absalom whom we anointed over us is dead in battle, and now, why are ye silent -- to bring back the king?'
