'Secret' in the Bible

that thy kindness may be in secret, and thy Father who is seeing in secret Himself shall reward thee manifestly.

But thou, when thou mayest pray, go into thy chamber, and having shut thy door, pray to thy Father who is in secret, and thy Father who is seeing in secret, shall reward thee manifestly.

that thou mayest not appear to men fasting, but to thy Father who is in secret, and thy Father, who is seeing in secret, shall reward thee manifestly.
