God has set many signs on the earth,

As well as in the heavens.

The oak of the forest,

The fruit of the tree,

The herb of the field—

All bear a sign

That seed hath been planted there.

For it is a decree of the Lord

That every tree, plant,

And herb bearing seed

Should bring forth of its kind,

And cannot come forth

After any other law or principle.

Prophet Joseph Smith
