Ecclesiastes 5:2

5:2 Do not be rash with your mouth or hasty in your heart to bring up a matter before God,

for God is in heaven and you are on earth!

Therefore, let your words be few.

Hosea 14:2

14:2 Return to the Lord and repent!

Say to him: “Completely forgive our iniquity;

accept our penitential prayer,

that we may offer the praise of our lips as sacrificial bulls.

Matthew 6:6-8

6:6 But whenever you pray, go into your room, close the door, and pray to your Father in secret. And your Father, who sees in secret, will reward you. 6:7 When you pray, do not babble repetitiously like the Gentiles, because they think that by their many words they will be heard. 6:8 Do not be like them, for your Father knows what you need before you ask him.
