Final answer:
The ship's guest may be crying due to feelings of sadness, loss, or disappointment. This could be caused by the failure of the firm, army, or ship as well as the transition from freedom to bondage or completing a journey.
Step-by-step explanation:
The ship's guest appears to be crying due to different circumstances in the various passages provided. It seems that in some cases, the guests may be crying due to feelings of sadness, loss, or disappointment. For example, in the passage where the injured captain is buried in profound dejection and indifference, the cause of his tears may be the failure of his firm, army, or ship. In another passage, the cry of hosts may be a result of being brought from their beloved Egyptian night into bondage. The ship's guest could also be crying due to the loss of a loved one or the completion of a journey, as depicted in the passage about the captain not answering and the ship's voyage being closed and done.
