Psalms 22:2

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

My tears have been my meat day and night, while they continually say unto me, Where is thy God?

O Lord God of my salvation, I have cried day and night before thee:

Night and day praying exceedingly that we might see your face, and might perfect that which is lacking in your faith?

I thank God, whom I serve from my forefathers with pure conscience, that without ceasing I have remembrance of thee in my prayers night and day;

And he was withdrawn from them about a stone’s cast, and kneeled down, and prayed, Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done. And there appeared an angel unto him from heaven, strengthening him. And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground. And when he rose up from prayer, and was come to his disciples, he found them sleeping for sorrow, And said unto them, Why sleep ye? rise and pray, lest ye enter into temptation.

And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God.

And he left them, and went away again, and prayed the third time, saying the same words.

As for me, I will call upon God; and the Lord shall save me. Evening, and morning, and at noon, will I pray, and cry aloud: and he shall hear my voice.

Thou hast covered thyself with a cloud, that our prayer should not pass through.

Also when I cry and shout, he shutteth out my prayer.

O Lord God of hosts, how long wilt thou be angry against the prayer of thy people?
