'Courses' in the Bible

And he sent them to Lebanon, ten thousand a month by courses: a month they were in Lebanon, and two months at home: and Adoniram was over the levy.

And he built the inner court with three courses of hewn stone, and a course of cedar beams.

And the great court round about had three courses of hewn stone, and a course of cedar beams; like as the inner court of the house of Jehovah, and the porch of the house.
