consist in moving about in the air, and suppose
that when they are reading _Jews_, they must understand _Gentiles_; and
when they read _Jerusalem_, they must understand the _church_; and if it
is said _earth_, it means _sky_; and for the coming of the _Lord_ they
must understand the progress of the _missionary societies_; and going up
to the mountain of the Lord's house, signifies a grand _class-meeting of
Methodists_."(599)

During the twenty-four years from 1821 to 1845, Wolff traveled
extensively: in Africa, visiting Egypt and Abyssinia; in Asia, traversing
Palestine, Syria, Persia, Bokhara, and India. He also visited the United
States, on the journey thither preaching on the island of St. Helena. He
arrived in New York in August, 1837; and after speaking in that city, he

clergy and citizens of Washington. The same honor was granted to me by the
members of the government of New Jersey and Pennsylvania, in whose
presence I delivered lectures on my researches in Asia, and also on the

mountains, the snow beating in his face, and his naked feet benumbed by

When warned against going unarmed among savage and hostile tribes, he
declared himself "provided with arms,"--"prayer, zeal for Christ, and

God and my neighbor in my heart, and the Bible is in my hand."(601) The
Bible in Hebrew and English he carried with him wherever he went. Of one
