Matthew 6:5, 6
<p><a href="http://bible.cc/matthew/6-5.htm" ><b>5</b></a>And when thou prayest, thou shalt not be as the hypocrites <i>are</i>: for they love to pray standing in the synagogues and in the corners of the streets,<b> that they may be seen of men.</b> Verily I say unto you, <b>They have their reward</b>.
 
<a href="http://bible.cc/matthew/6-6.htm" ><b>6</b></a>But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, <b>pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.</b>
 
What the places were which they chose for their devotions; they prayed in the synagogues, which were indeed proper places for public prayer, but not for personal. They pretended hereby to do honour to the place of their assemblies, but intended to do honour to themselves.
 
<b>Public places are not proper for private solemn prayer</b></p>
