'Eater' in the Bible

He said to them, "Out of the eater came forth food. Out of the strong came forth sweetness." They couldn't in three days declare the riddle.

For as the rain comes down and the snow from the sky, and doesn't return there, but waters the earth, and makes it bring forth and bud, and gives seed to the sower and bread to the eater;

All your fortresses will be like fig trees with the first-ripe figs: if they are shaken, they fall into the mouth of the eater.
