'Eater' in the Bible

And he saith to them: 'Out of the eater came forth meat, And out of the strong came forth sweetness;' and they were not able to declare the riddle in three days.

For, as come down doth the shower, And the snow from the heavens, And thither returneth not, But hath watered the earth, And hath caused it to yield, and to spring up, And hath given seed to the sower, and bread to the eater,

All thy fortresses are fig-trees with first-fruits, If they are shaken, They have fallen into the mouth of the eater.
