Who was the first that forged the deadly blade? Of rugged steel his savage soul was made.

是谁第一个铸造出了杀人的利刃？他粗莽的心灵必如顽铁一般！

Those friends thou hast, and their adoption tried, Grapple them unto thy soul with hoops of steel; But do not dull thy palm with entertainment; Of each new-hatch'd, unfledg'd comrade.

相知有素的朋友，应该用钢圈箍在你的灵魂上，可是不要对每一个泛泛的新知滥施你的交情。
