Psalms 86:3

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 Psalm 41:10 .

for I cry unto thee daily ; or "all the day"; every day, and several times in a day, Psalm 55:17 constant and importunate prayer is the duty of saints, and available with God, 1 Thessalonians 5:17 . Christ was much in the exercise of it, Luke 6:12 .
