After many weary steps, we came to Wachusett, where he was; and glad I was to see him. He asked me when I washed myself. I told him, "Not this month." Then he fetched me some water himself and bid me wash, and gave me the glass to see how I looked; and bid his squaw give me something to eat. So she gave me a mess of beans and meat, and a little ground nut cake. I was wonderfully revived with this favor shown to me: "He made them also to be pitied of all those that carried them captives" (Psalm 106:46).
