Daniel knew that the decree was signed. He went into his house. His windows were open in his chamber toward Jerusalem. He kneeled upon his knees three times a day, and prayed, and gave thanks before his God, like he did before.

Early in the morning, long before daybreak, Jesus awoke and went into the wilderness to pray.

After he left he went to the mountain to pray.

He spoke an illustration to them emphasizing the need to pray and not become tired:

Peter and John went up to the temple at the hour of prayer. It was the ninth hour.

About the ninth hour of the day he clearly saw a vision. An angel of God came to him and said, Cornelius.

With prayer and supplication pray at all times in the Spirit. Watch with all perseverance and supplication for all the holy ones.

Pray without ceasing.

Cry

Yes I cry for Help! I am being attacked! But I get no response. I call for help, but there is no justice.

Even when I send up a cry for help, he shuts out my prayer.

In the days of his life on earth, when he [Christ] offered up prayers and supplications with strong crying and tears to the one who was able to save him out of death, and was heard because of his godly reverence. (Galatians 1:1) (Psalm 69:13)
