'Secret' in the Bible

Those who try to hide their plans from the Lord are as good as dead, who do their work in secret and boast, "Who sees us? Who knows what we're doing?"

I will give you hidden treasures, riches stashed away in secret places, so you may recognize that I am the Lord, the one who calls you by name, the God of Israel.

I have not spoken in secret, in some hidden place. I did not tell Jacob's descendants, 'Seek me in vain!' I am the Lord, the one who speaks honestly, who makes reliable announcements.

Approach me! Listen to this! From the very first I have not spoken in secret; when it happens, I am there." So now, the sovereign Lord has sent me, accompanied by his spirit.
