'Tender' in the Bible

Their inhabitants have become powerless,dismayed, and ashamed.They are plants of the field,tender grass,grass on the rooftops,blasted by the east wind.

Because thine heart was tender, and thou hast humbled thyself before the LORD, when thou heardest what I spake against this place, and against the inhabitants thereof, that they should become a desolation and a curse, and hast rent thy clothes, and wept before me; I also have heard thee, saith the LORD.
