'Smallest' in the Bible

Solemnly I tell you that until Heaven and earth pass away, not one iota or smallest detail will pass away from the Law until all has taken place.

It is the smallest of all seeds, and yet when full-grown it is larger than any herb and forms a tree, so that the birds come and build in its branches."

It is like a mustard-seed, which, when sown in the earth, is the smallest of all the seeds in the world;

But it is easier for earth and sky to pass away than for one smallest detail of the Law to fall to the ground.
