Charles Ellicott Commentary Acts 21:3

"And when we had come in sight of Cyprus, leaving it on the left hand, we sailed unto Syria, and landed at Tyre; for there the ship was to unlade her burden." — Acts 21:3 (ASV)

When we had discovered Cyprus . . .—The use of a technical term here is specially characteristic of St. Luke. Here the meaning is that, as soon as they sighted Cyprus, they stood to the southeast, and so had it on their left as they continued their voyage to Syria. At Tyre they had again to change their ship. On the position and history of Tyre, see Note on Matthew 11:21.
