This familiar passage creates a beautiful word "picture."
While it is emphasizing the Lord's desire that Israel have a common to everyone Nation in the millennium,
it is assuredly not omitting a tangent blessing and truth about prayer itself.
Word pictures are quite common in scripture.
Bread of life, Rock of our salvation, fortress, shield, horn and many others communicate ideas
through objects we can see in the mind's eye that becomes vivid transcending concepts.

In studying prayer we'd like to make some biblical observations about prayer and houses!

We'd like to plan to illustrate each room with scriptural relational content.

Rooms in a typical Imaginary HOME

Living Room--  Where life is lived! Prayer about life and living at home!
Dining Room-- Matthew 5:6 "Blessed are they who HUNGER AND THIRST"
Master Bed Room-- SLEEP "of a laboring man is" SWEET; and right thinking is by a min "stayed on God."
Nursery-- CHILDREN are His heritage, given as temporary arrows to shoot.
Children's Bedroom-- A Home's most cherished and FUTURE earthly HOPE!
Guest Bedroom-- Hospitality is a part of God's expectation for His People.
Study-- 2 Ti 2:15 Studying is a blessing, and liberating art, as also a duty showing us approved of God
Library-- BOOKS and reading for the soul, and certainly a schoolroom of study or a place for quiet relaxation, seclusion, and rest
Chapel/ Attic--THE SECRET PLACE a place for worship, daily devotion and preparation.
Family Room/ Den--Keeping the family recreation is vital and a great challenge, Family is a heritage of the USA.
Hall/ Stairway--passage or gateway to other room (s), and a navigator to all the issues of life.
Front Porch-- Gives the view of the outside world, but also the first place to welcome guests.
Back Porch-- A place to prepare to reenter the house.
Rest Room-- A critical place to eliminate wastes of life and to cleanse ourselves before appearing to others.
Basement-- the storage place of archived family matters, or a place to do family activity
Boiler HVAC Room-- the powerhouse of living comforts keeping us warm in winter and cool in summer.
UPSTAIRS/ VERANDA with PARAPET [par·a·pet] As a porch on lower level,
the upper floor deck provide a protective view providing security and forewarning of storms.

The parapet, a "low, protective wall along the edge of a roof, bridge, or balcony" provides self -protection..
