'Seen' in the Bible

Now faith is the assurance of things hoped for, the conviction of things not seen.

By faith we understand that the worlds were prepared by the word of God, so that what is seen was not made out of things which are visible.

By faith Noah, being warned by God about things not yet seen, in reverence prepared an ark for the salvation of his household, by which he condemned the world, and became an heir of the righteousness which is according to faith.

All these died in faith, without receiving the promises, but having seen them and having welcomed them from a distance, and having confessed that they were strangers and exiles on the earth.
