Daniel prayed three times daily with his window open toward Jerusalem. Paul tells us to "Pray without ceasing." (1 Thess 5:17)... 522 - 7-4

“The tallit, Jewish prayer shawl, is worn over the outer clothes during the morning prayers (Shacharit) and worn during all prayers on Yom Kippur. The tallit has special twined and knotted fringes known as tzitzit attached to its four corners. Most traditional tallitot are made of wool. Tallitot are often first worn by children on their Bar Mitzvahs. In orthodox, Ashkenazi circles, a Tallit is customarily presented to a groom before marriage as part of the dowry.”

Although Daniel knew that being seen praying could cost him his life he followed his daily practice of donning his prayer shawl, opening his window and facing Jerusalem as he prayed three times a day. I feel confident that Daniel also prayed ceaselessly throughout the day.

To me there is value both in prescribed prayer time with God and with praying ceaselessly. I pray both as I wake up and as I go to bed. Often in the morning I comment to God that we are still here rather than having been rapture during the night. At night I often suggest that this would be a wonderful night for Jesus to come and rapture his Church. I also pray silently several times a day. I may pray for Israel or maybe something as simple as a thank you. While most of my prayers are silent, when I am enjoying a meal in public with my BAC friends we do offer a quiet prayer of Thanksgiving.

Jesus had quite a bit to say about prayer in the book of Matthew. He referred to the scribes and Pharisees as hypocrites.

Matthew 6:5-6, “And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward. But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.”

Perhaps by downing a prayer shawl the Jewish supplicant is entering a facsimile to his closet.
Matthew 26:5-7, "But all their works they do for to be seen of men: they make broad their phylacteries, and enlarge the borders of their garments, And love the uppermost rooms at feasts, and the chief seats in the synagogues, And greetings in the markets, and to be called of men, Rabbi, Rabbi."

Luke 12:3, “Therefore whatsoever ye have spoken in darkness shall be heard in the light; and that which ye have spoken in the ear in closets shall be proclaimed upon the housetops.”
What a wonderful testament this is to the power of prayer spoken quietly to God.

Added later:

Here Jesus could be speaking to the Roman Catholic Church known for repetition in their liturgy. Matthew 6:7 "But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.” And what could be more pagan and repetitious then the hundreds of repetition of Hail Mary? I was surprised by the following article that included: “The New Testament depicts Mary as the Ark of the New Covenant, the New Eve, the Temple Gate surrounding the New Temple, Christ, and the builder of that New Temple.”
