'Conceal' in the Bible

Then they will begin to say to the mountains, ‘Fall on us!’ and to the hills, ‘Cover us!’

And he confessed [truthfully] and did not deny [that he was only a man], but acknowledged, “I am not the Christ (the Messiah, the Anointed)!”

on that day when, as my gospel proclaims, God will judge the secrets [all the hidden thoughts and concealed sins] of men through Christ Jesus.

For as you well know, we never came with words of flattery nor with a pretext for greed—God is our witness—

As God’s slaves, live as free people, but don’t use your freedom as a way to conceal evil.
