'Declareth' in the Bible

For who knoweth what is good for a man in life, the number of the days of the life of his vanity, and he maketh them as a shadow? for who declareth to man what is after him under the sun?

For he knoweth not that which shall be, for when it shall be who declareth to him?

Even in thy mind a king revile not, And in the inner parts of thy bed-chamber Revile not the rich: For a fowl of the heavens causeth the voice to go, And a possessor of wings declareth the word.
