“The words of the mouth of the wise are grace; but the lips of the fool will swallow him” (Ecclesiastes 10:12). “The words of the mouth of the wise are grace” – this is Cyrus, king of Persia, who said: “Any among you from His entire people, may his God be with him, and he may go up [to Jerusalem]” (Ezra 1:3). “But the lips of the fool will swallow him” – as he recanted his words and retracted them.65Cyrus initially allowed the rebuilding of the Temple, but he is also identified with Artaḥshasta, who ordered that the construction of the Temple be stopped (see Ezra, chap. 4; Esther Rabba 1:3).
