'Offering' in the Bible

Let there be no sound before the Lord God: for the day of the Lord is near: for the Lord has made ready an offering, he has made his guests holy.

And it will come about in the day of the Lord's offering, that I will send punishment on the rulers and the king's sons and all who are clothed in robes from strange lands.

From beyond the rivers of Ethiopia my suppliants, even the daughter of my dispersed, shall bring mine offering.
