'Wheat' in the Bible

whose winnowing fan is in his hand, and he shall thoroughly purge his threshing-floor, and shall gather his wheat into the garner, but the chaff he will burn with fire unquenchable.

but while men slept, his enemy came and sowed darnel amongst the wheat, and went away.

But he said, No; lest in gathering the darnel ye should root up the wheat with it.

Suffer both to grow together unto the harvest, and in time of the harvest I will say to the harvestmen, Gather first the darnel, and bind it into bundles to burn it; but the wheat bring together into my granary.
