'Solid' in the Bible

And God said, Let there be a solid arch stretching over the waters, parting the waters from the waters.

By your breath the waves were massed together, the flowing waters were lifted up like a pillar; the deep waters became solid in the heart of the sea.

And though by this time it would be right for you to be teachers, you still have need of someone to give you teaching about the first simple rules of God's revelation; you have become like babies who have need of milk, and not of solid food.

But solid food is for men of full growth, even for those whose senses are trained by use to see what is good and what is evil.
