Had discovered Cyprus. (See Barnes on Acts 4:36).

Into Syria. (See Barnes on Matthew 4:24).

And landed at Tyre. (See Barnes on Matthew 11:21).

To unlade her burden. Her cargo. Tyre was formerly one of the most commercial cities of the world; and it is probable, that in the time of Paul its commercial importance had not entirely ceased.
