'Once' in the Bible

but Hannah did not go up with them. Instead she told her husband, "Once the boy is weaned, I will bring him and appear before the Lord, and he will remain there from then on."

Once she had weaned him, she took him up with her, along with three bulls, an ephah of flour, and a container of wine. She brought him to the Lord's house at Shiloh, even though he was young.

Once the bull had been slaughtered, they brought the boy to Eli.

When you enter the town, you can find him before he goes up to the high place to eat. The people won't eat until he arrives, for he must bless the sacrifice. Once that happens, those who have been invited will eat. Now go on up, for this is the time when you can find him!"

Now once again there was war. So David went out to fight the Philistines. He defeated them thoroughly and they ran away from him.

Jonathan once again took an oath with David, because he loved him. In fact Jonathan loved him as much as he did his own life.

So David asked the Lord once again. But again the Lord replied, "Arise, go down to Keilah, for I will give the Philistines into your hand."
