'Wheat' in the Bible

Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire.

But while men slept, his enemy came and sowed tares among the wheat, and went his way.

But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them.

Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.
