'Eater' in the Bible

So he said to them,“Out of the eater came something to eat,And out of the strong came something sweet.”And they could not solve the riddle in three days.

“For as the rain and snow come down from heaven,And do not return there without watering the earth,Making it bear and sprout,And providing seed to the sower and bread to the eater,

All your fortresses are [nothing but] fig trees with ripe figs—When shaken they fall into the mouth of the eater.
