read the paragraph

Then, being much troubled in mind, I said to my men, “My friends, it is not right that one or two of us alone should know the prophecies that Circe has made me, I will therefore tell you about them, so that whether we live or die we may do so with our eyes open. First she said we were to keep clear of the Sirens…. Therefore, take me and bind me to the crosspiece halfway up the mast... with a bond so fast that I cannot possibly break away.... If I beg and pray you to set me free, then bind me more tightly still.”
