What is the message the seaman gives Pearl to give to Hester?

From the text:

"Then tell her," rejoined he, "that I spake again with the black-a-visaged, hump-shouldered old doctor, and he engages to bring his friend, the gentleman she wots of, aboard with him. So let thy mother take no thought, save for herself and thee. Wilt thou tell her this, thou witch-baby?"
