'Myrtle' in the Bible

I give in a wilderness the cedar, Shittah, and myrtle, and oil-tree, I set in a desert the fir-pine and box-wood together.

Instead of the thorn come up doth fir, Instead of the brier come up doth myrtle, And it hath been to Jehovah for a name, For a sign age-during -- it is not cut off!
