Psalm 86:3

Be merciful unto me, O God, be merciful unto me: for my soul trusteth in thee: yea, in the shadow of thy wings will I make my refuge, until these calamities be overpast.

Evening, and morning, and at noon, will I pray, and cry aloud: and he shall hear my voice.

And she was a widow of about fourscore and four years, which departed not from the temple, but served God with fastings and prayers night and day.

And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
