'Enemy' in the Bible

"You have heard that it was said, 'Thou shalt love thy neighbour and hate thine enemy.'

but during the night his enemy comes, and over the first seed he sows darnel among the wheat, and goes away.

"'Some enemy has done this,' he said. "'Shall we go, and collect it?' the men inquire.

The enemy who sows the darnel is *the Devil*; the harvest is the Close of the Age; the reapers are the angels.
