'Once' in the Bible

So Abner said to Asahel {once again}, "{For your own sake}, turn aside {from following me}. Why should I strike you down to the ground? How could I {show my face} to Joab your brother?"

{Once again} [the] Philistines came up and spread out in the Valley of Rephaim.

Once again there [was] battle at Gath, and there [was] {a man of great size}. The fingers of his hand and the toes of his feet [were] six and six, twenty-four in number. He [was] also born to the Raphah.
