'Business' in the Bible

So now, if it seems good to the king, let search be made in the king's store-house at Babylon, to see if it is true that an order was given by Cyrus the king for the building of this house of God at Jerusalem, and let the king send us word of his pleasure in connection with this business.

Up, now! for this is your business, and we are with you; take heart and do it.

Then all the men of Judah and Benjamin came together to Jerusalem before three days were past; it was the ninth month, on the twentieth day of the month; and all the people were seated in the wide square in front of the house of God, shaking with fear because of this business and because of the great rain.

However, the people are numerous and it is the rainy season. We are unable to stand here outside. Furthermore, this business cannot be resolved in a day or two, for we have sinned greatly in this matter.
