'Thing' in the Bible

"So now, take your positions and watch this great thing that the Lord is about to do in your sight.

Then the men of the garrison said to Jonathan and his armor bearer, "Come on up to us so we can teach you a thing or two!" Then Jonathan said to his armor bearer, "Come up behind me, for the Lord has given them into the hand of Israel!"

He said to his men, "May the Lord keep me far away from doing such a thing to my lord, who is the Lord's chosen one, by extending my hand against him. After all, he is the Lord's chosen one."

Since you did not obey the Lord and did not carry out his fierce anger against the Amalekites, the Lord has done this thing to you today.
