'Pair' in the Bible

and [they came also] to offer a sacrifice according to what is said in the Law of the Lord [to be appropriate for a family of modest means], “a pair of turtledoves or two young pigeons.”

When He (the Lamb) broke open the third seal, I heard the third living creature call out, “Come.” I looked, and behold, a black horse [of famine]; and the rider had in his hand a pair of scales (a balance).
