Listen to Your servant’s prayer and his petition,Lord my God,so that You may hear the cry and the prayerthat Your servant prays before You today,

May Your eyes be open to Your servant’s petitionand to the petition of Your people Israel,listening to them whenever they call to You.

May my words I have made my petition with before the Lord be near the Lord our God day and night, so that He may uphold His servant’s cause and the cause of His people Israel, as each day requires,
