Be merciful unto me, O Lord
In my distressed and miserable condition, being an object of mercy, pity, and compassion; this petition is used by Christ in ( Psalms 41:10 )
for I cry unto thee daily;
or "all the day"; every day, and several times in a day, ( Psalms 55:17 ) constant and importunate prayer is the duty of saints, and available with God, ( 1 Thessalonians 5:17 ) ( Luke 18:1-7 ) . Christ was much in the exercise of it, ( Luke 6:12 ) .
