'Secret' in the Bible

so that your giving will be in secret; and your Father who sees what is done in secret will reward you.

But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you.

so that your fasting will not be noticed by men, but by your Father who is in secret; and your Father who sees what is done in secret will reward you.
