'Wild' in the Bible

Now John wore clothing made from camel's hair with a leather belt around his waist, and his diet consisted of locusts and wild honey.

And if this is how God clothes the wild grass, which is here today and tomorrow is tossed into the fire to heat the oven, won't he clothe you even more, you people of little faith?

It is the smallest of all the seeds, but when it has grown it is the greatest garden plant and becomes a tree, so that the wild birds come and nest in its branches."
