In Psalm 19:12-14, we read:
12 Who can understand his errors? cleanse thou me from secret faults.
13 Keep back thy servant also from presumptuous sins; let them not have dominion over me: then shall I be upright, and I shall be innocent from the great transgression.
14 Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer.
The Book of Psalms is the 19th book of the Bible. So the identifier of Psalm 19:12-14 is 153.
CONCLUSION: When we pray the Lord’s Prayer, we petition our Father to forgive our secret and presumptuous sins, and to let the words of our mouth and the meditation of our heart be acceptable in His sight,
