'Courses' in the Bible

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 men subject to forced labor.

He built the inner court with three courses of cut stone, and a course of cedar beams.

The great court around had three courses of cut stone, and a course of cedar beams; like as the inner court of the house of Yahweh, and the porch of the house.
