There is no good reason to believe that Asaad was actuated, at this time, by higher than worldly motives.
At the close of his connection with Mr.King, he made another effort to secure employment from his Patriarch.

Not succeeding, he became Arabic teacher to Mr.Fisk; at the same time assisting Mr.King, then about leaving the country, in preparing his celebrated "Farewell Letter" to his Arab friends.

After having put this into neat Arabic style, he made a large number of copies, to be sent to different parts of the country.
On the day of Mr.King's departure from Beirut, Asaad, at the request of the mission, commenced an Arabic grammar-school for native boys.

His leisure hours were devoted to composing a refutation of the doctrines contained in Mr.King's "Farewell Letter." This is his own account: "When I was copying the first rough draught of my reply, and had arrived at the last of the reasons, which, he said, prevented his becoming a member of the Roman Catholic Church; namely, their teaching it to be wrong for the commom people to possess or to read the Word of God, I observed that the writer brought a proof against the doctrine from the prophet Isaiah; namely, that if they spoke not according to the law and to the testimony, it was because there was no light in them.
"While I was endeavoring to explain this passage according to the views of the Roman Catholic Church, with no other object than the praise of men and other worldly motives, I chanced to read the twenty-ninth chapter of Isaiah from the fifteenth verse to the end.
I read and was afraid.

I meditated upon the chapter a long while, and feared that I was doing what I did with a motive far different from the only proper one,--the glory and pleasure of God.
