MAT:6:5-6
And when you make your prayers, be not like the false-hearted men, who take pleasure in getting up and saying their prayers in the Synagogues and at the street turnings so that they may be seen by men. Truly I say to you, They have their reward.But when you make your prayer, go into your private room, and, shutting the door, say a prayer to your Father in secret, and your Father, who sees in secret, will give you your reward.
