Matthew 6:5; Matthew 21:42

5 And when thou prayest , thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you , They have their reward.
42 Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected , the same is become the head of the corner: this is the Lord's doing , and it is marvellous in our eyes?
