Mark 12:38-40
And in his teaching he said, “Beware of the scribes, who like to walk around in long robes and like greetings in the marketplaces and have the best seats in the synagogues and the places of honor at feasts, who devour widows’ houses and for a pretense make long prayers. They will receive the greater condemnation.”
Matthew 6: 1-8
“Beware of practicing your righteousness before other people in order sto be seen by them, for then you will have no reward from your Father who is in heaven. “Thus, when you give to the needy, sound no trumpet before you, as the hypocrites do in the synagogues and in the streets, that they may be praised by others. Truly, I say to you, they have received their reward. But when you give to the needy, do not let your left hand know what your right hand is doing, so that your giving may be in secret. And your Father who sees in secret will reward you. “And when you pray, you must not be like the hypocrites. For they love to stand and pray in the synagogues and at the street corners, that they may be seen by others. Truly, I say to you, they have received their reward. But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you. “And when you pray, do not heap up empty phrases as the Gentiles do, for they think that they will be heard for their many words. Do not be like them, for your Father knows what you need before you ask him. --ESV
