'Lines' in the Bible

And he smote Moab, and measured them with a line, casting them down to the ground; even with two lines measured he to put to death, and with one full line to keep alive. And so the Moabites became David's servants, and brought gifts.

When Joab observed that the battle lines were set up to oppose him both in front and behind, he appointed the best troops in Israel and arrayed them to oppose the Arameans,

The rest of the army he placed into the hand of his brother Abishai, who {arranged them in battle lines} to meet the {Ammonites}.

David [was] told, so he gathered all Israel and crossed over the Jordan and came to Helam. Aram {arranged themselves in battle lines} to meet David, and they fought with him.
