What does 2 Samuel 21:2 mean?

And the king called the Gibeonites, and said unto them (now the Gibeonites were not of the children of Israel, but of the remnant of the Amorites; and the children of Israel had sworn unto them: and Saul sought to slay them in his zeal for the children of Israel and Judah);

And the king called the Gibeonites, and said unto them; (now the Gibeonites were not of the children of Israel, but of the remnant of the Amorites; and the children of Israel had sworn unto them: and Saul sought to slay them in his zeal to the children of Israel and Judah.)

And the king called the Gibeonites, and said unto them (now the Gibeonites were not of the children of Israel, but of the remnant of the Amorites; and the children of Israel had sworn unto them: and Saul sought to slay them in his zeal for the children of Israel and Judah);

Then the king sent for the Gibeonites; (now the Gibeonites were not of the children of Israel, but were the last of the Amorites, to whom the children of Israel had given an oath; but Saul, in his passion for the children of Israel and Judah, had made an attempt on their lives:)

And the king calleth for the Gibeonites, and saith unto them--as to the Gibeonites, they <FI>are<Fi> not of the sons of Israel, but of the remnant of the Amorite, and the sons of Israel had sworn to them, and Saul seeketh to smite them in his zeal for the sons of Israel and Judah--

Then the king, calling for the Gabaonites, said to them: (Now the Gabaonites were not of the children of Israel, but the remains of the Amorrhites: and the children of Israel had sworn to them, and Saul sought to slay them out of zeal, as it were for the children of Israel and Juda:)

And the king called the Gibeonites, and spoke to them. (Now the Gibeonites were not of the children of Israel, but of the remainder of the Amorites; and the children of Israel had sworn to them; and Saul sought to smite them in his zeal for the children of Israel and Judah.)
