'Thing' in the Bible

Blessed be the LORD God of our fathers, which hath put such a thing as this in the king's heart, to beautify the house of the LORD which is in Jerusalem:

And when I heard this thing, I rent my garment and my mantle, and plucked off the hair of my head and of my beard, and sat down astonied.

And Shechaniah the son of Jehiel, one of the sons of Elam, answered and said unto Ezra, We have trespassed against our God, and have taken strange wives of the people of the land: yet now there is hope in Israel concerning this thing.

But the people are many, and it is a time of much rain, and we are not able to stand without, neither is this a work of one day or two: for we are many that have transgressed in this thing.
