ahhh, proverbs.

The purposes of a man's heart are deep waters,

    but a man of understanding draws them out.

The lamp of the LORD searches the spirit of a man;

    it searches out his inmost being.

There is no wisdom, no insight, no plan

    that can succeed against the LORD.

The king's heart is in the hand of the LORD;

    he directs it like a watercourse wherever he pleases.
