Hebrews 10:25
"Not forsaking the assembling of ourselves together, as the manner of some is,but exhorting one another; and so much the more as you see the day approaching"
5 "And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full.
6 But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
