“As the rain

Comes down from heaven,

As the snow

Comes down from heaven,

They do not return there

Until they have watered the earth.

They make it come forth.

They make it sprout.

They give seed to the sower.

They give bread to the eater.

Thus shall my word

Go out from my mouth.

It shall not return to me empty.

But it shall accomplish

That which I purpose.

It will succeed

In the thing

For which I sent it.”

Second Isaiah emphasizes the importance of the word of Yahweh. Water and snow do not return empty handed to heaven. Apparently, these biblical writers were aware of osmosis. The water and the snow helped bring about germination of the sprouts from the ground. They made the seeds of the sower grow. They assisted in making bread for humans to eat. So too, the word of Yahweh will not come back empty either. His words must accomplish their purpose. His word will be successful in making things grow.
