Adam Clarke

And the oil stayed - While there was a vessel to fill, there was oil sufficient; and it only ceased to flow when there was no vessel to receive it. This is a good emblem of the grace of God. While there is an empty, longing heart, there is a continual overflowing fountain of salvation. If we find in any place or at any time that the oil ceases to flow, it is because there are no empty vessels there, no souls hungering and thirsting for righteousness. We find fault with the dispensations of God's mercy, and ask, Why were the former days better than these? Were we as much in earnest for our salvation as our forefathers were for theirs, we should have equal supplies, and as much reason to sing aloud of Divine mercy.
