'Course' in the Bible

We put out to sea from Troas and sailed a straight course to Samothrace, the next day to Neapolis,

After we tore ourselves away from them, we put out to sea, and sailing a straight course, we came to Cos, on the next day to Rhodes, and from there to Patara.

Of course, I myself was convinced that it was necessary to do many things hostile to the name of Jesus the Nazarene.

For who is our hope or joy or crown to boast of before our Lord Jesus at his coming? Is it not of course you?

And the tongue is a fire! The tongue represents the world of wrongdoing among the parts of our bodies. It pollutes the entire body and sets fire to the course of human existence -- and is set on fire by hell.
