The Bible does not tell us exactly at what time each day He prayed. It does, however, suggest that he was known for praying at different times within a full 24 hour period. Aside from the numerous references to him praying, likely at different times throughout the day, Mk 1:35 shows him having risen early, while it was still dark out, and praying. In Luke 6:12-13 he prays throughout the night and into the morning. Luke 5:16 gives reason for the need to pray often, that more and more people came to hear him, and to be healed of their infirmities.
