Psalms 40:9-10

¶I have proclaimed good news of righteousness [and the joy that comes from obedience to You] in the great assembly; Behold, I will not restrain my lips [from proclaiming Your righteousness], As You know, O LORD. I have not concealed Your righteousness within my heart; I have proclaimed Your faithfulness and Your salvation. I have not concealed Your lovingkindness and Your truth from the great assembly. [Acts 20:20, 27]
