'Stalk' in the Bible

He slept and dreamed a second time: and behold, seven heads of grain came up on one stalk, healthy and good.

I saw in my dream, and behold, seven heads of grain came up on one stalk, full and good:

For they sow the wind, and they will reap the whirlwind. He has no standing grain. The stalk will yield no head. If it does yield, strangers will swallow it up.
