'Declare' in the Bible

For he has absolutely no knowledge what will happen, since who can declare to him when it will come about?

For all this I considered in my heart even to declare all this, that the righteous, and the wise, and their works, are in the hand of God: no man knoweth either love or hatred by all that is before them.

And the fool multiplieth words: 'Man knoweth not that which is, And that which is after him, who doth declare to him?'
