Matthew 6:6

But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly.

Psalm 27:5

For in the time of trouble

He shall hide me in His pavilion;

In the secret place of His tabernacle

He shall hide me;

He shall set me high upon a rock.
