Psalm 51:1-17 New Revised Standard Version (NRSV)
Prayer for Cleansing and Pardon
To the leader. A Psalm of David, when the prophet Nathan came to him, after he had gone in to Bathsheba.
1 Have mercy on me, O God,
3 For I know my transgressions,
6 You desire truth in the inward being;[a]
10 Create in me a clean heart, O God,
13 Then I will teach transgressors your ways,
15 O Lord, open my lips,
Matthew 6:1-6 New Revised Standard Version (NRSV)
6 “Beware of practicing your piety before others in order to be seen by them; for then you have no reward from your Father in heaven.
2 “So whenever you give alms, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, so that they may be praised by others. Truly I tell you, they have received their reward. 3 But when you give alms, do not let your left hand know what your right hand is doing, 4 so that your alms may be done in secret; and your Father who sees in secret will reward you.[a]
5 “And whenever you pray, do not be like the hypocrites; for they love to stand and pray in the synagogues and at the street corners, so that they may be seen by others. Truly I tell you, they have received their reward. 6 But whenever 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.[b]
Matthew 6:16-21 New Revised Standard Version (NRSV)
16 “And whenever you fast, do not look dismal, like the hypocrites, for they disfigure their faces so as to show others that they are fasting. Truly I tell you, they have received their reward. 17 But when you fast, put oil on your head and wash your face, 18 so that your fasting may be seen not by others but by your Father who is in secret; and your Father who sees in secret will reward you.[a]
19 “Do not store up for yourselves treasures on earth, where moth and rust[b] consume and where thieves break in and steal; 20 but store up for yourselves treasures in heaven, where neither moth nor rust[c] consumes and where thieves do not break in and steal. 21 For where your treasure is, there your heart will be also.
