'Stored' in the Bible

The [intrinsically] good man produces what is good and honorable and moral out of the good treasure [stored] in his heart; and the [intrinsically] evil man produces what is wicked and depraved out of the evil [in his heart]; for his mouth speaks from the overflow of his heart.

in whom are hidden all the treasures of wisdom and knowledge [regarding the word and purposes of God].

But by His word the present heavens and earth are being reserved for fire, being kept for the day of judgment and destruction of the ungodly people.
