'Grass' in the Bible

And when he came to Lehi, the Philistines came out, meeting him with loud cries; then the spirit of the Lord came rushing on him, and the cords on his arms became like grass which has been burned with fire, and the bands came falling off his hands.

But we have dry grass and food for our asses, as well as bread and wine for me, and for the woman, and for the young man with us: we have no need of anything.
