'Course' in the Bible

As John was fulfilling his course, he said, 'What do you suppose that I am? I am not he. But behold, one comes after me the sandals of whose feet I am not worthy to untie.'

Setting sail therefore from Troas, we made a straight course to Samothrace, and the day following to Neapolis;

When it happened that we had parted from them and had set sail, we came with a straight course to Cos, and the next day to Rhodes, and from there to Patara.
