'Courses' in the Bible

Your neck is like the tower of David built with courses of stones; one thousand shields are hung on it -- all shields of valiant warriors.

"But tell the people of Jerusalem that the Lord says, 'I will give you a choice between two courses of action. One will result in life; the other will result in death.

The sun and moon stand still in their courses; the flash of your arrows drives them away, the bright light of your lightning-quick spear.
