'Difference' in the Bible

So Moses took the ransom money to account for the difference in the total number of those redeemed by the descendants of Levi.

I'm now 80 years old! I can hardly tell the difference between what tastes good or bad! I can't tell what I eat or drink! I can't hear the voice of men and women when they sing! So why should your servant be an added burden to your majesty the king?

When you return, you will see the difference between the righteous and the wicked, and between the one who serves God and the one who does not."
