'Circle' in the Bible

So David arose early in the morning and left the flock with a keeper and took the supplies and went as Jesse had commanded him. And he came to the circle of the camp while the army was going out in battle array shouting the war cry.

David then arose and came to the place where Saul had camped. And David saw the place where Saul lay, and Abner the son of Ner, the commander of his army; and Saul was lying in the circle of the camp, and the people were camped around him.

So David and Abishai came to the people by night, and behold, Saul lay sleeping inside the circle of the camp with his spear stuck in the ground at his head; and Abner and the people were lying around him.

When David inquired of the Lord, He said, “You shall not go directly up; circle around behind them and come at them in front of the balsam trees.

David inquired again of God, and God said to him, “You shall not go up after them; circle around behind them and come at them in front of the balsam trees.

“He has inscribed a circle on the surface of the watersAt the boundary of light and darkness.

“When He established the heavens, I was there,When He inscribed a circle on the face of the deep,

I did not sit in the circle of merrymakers,Nor did I exult.Because of Your hand upon me I sat alone,For You filled me with indignation.
