THE KING MAY NEITHER JUDGE NOR BE JUDGED, TESTIFY NOR BE TESTIFIED AGAINST. HE MAY NOT PERFORM HALIZAH NOR MAY IT BE PERFORMED TO HIS WIFE. HE MAY NOT PERFORM YIBBUM, NOR MAY IT BE PERFORMED TO HIS WIFE. R. JUDAH SAID: IF HE WISHES TO PERFORM HALIZAH OR YIBBUM, HE SHALL BE REMEMBERED FOR GOOD. BUT THEY [THE RABBIS] SAID: [EVEN IF HE WISHES] HE IS NOT LISTENED TO; NOR MAY ANY ONE MARRY HIS WIDOW. R. JUDAH SAID: A KING MAY MARRY A KING'S WIDOW, FOR SO WE FIND IN THE CASE OF DAVID WHO MARRIED THE WIDOW OF SAUL, AS IT IS WRITTEN, AND I GAVE THEE THY MASTER'S HOUSE AND THY MASTER'S WIVES INTO THY BOSOM. (Sanhedrin 19a)
