"do you not know, have you not heard ..."

Who has measured the waters in the hollow of his hand, or with the breadth of his hand marked off the heavens?
Who has held the dust of the earth in a basket, or weighed the mountains on the scales and the hills in a balance?

... He sits enthroned above the circle of the earth, and its people are like grasshoppers.
He stretches out the heavens like a canopy, and spreads them out like a tent to live in.
He brings princes to naught and reduces the rulers of this world to nothing.
No sooner are they planted, no sooner are they sown, no sooner do they take root in the ground, than he blows on them and they wither, and a whirlwind sweeps them away like chaff.

... the LORD is the everlasting God, the Creator of the ends of the earth.
He will not grow tired or weary, and his understanding no one can fathom.
He gives strength to the weary and increases the power of the weak.
Even youths grow tired and weary, and young men stumble and fall:
but those who hope in the LORD will renew their strength.
They will soar on wings like eagles: they will run and not grow weary, they will walk and not be faint.

from Isaiah 40 (NIV)
