Mezuzah

 Mezuzah, Deuteronomy 6: 3-9

Hear therefore, O Israel, and observe to do it; that it may be well with thee, and that ye may increase mightily, as the Lord God of thy fathers hath promised thee in the land that flowery with milk and honey.

Hear O Israel; The Lord our God is on Lord

And thou shalt love the Lord thy God with all thine heart, and with all thy soul and with all thy might.

And these words, which I commend thee this day, shall be in thine heart.

And though shalt teach them diligently unto thy children, and slat talk of them when thou fittest in thine house, and when thou

walkest by the way, and when thou liest down, and when thou risest up.

And thou shalt bind them for a sign upon thine hand, and they shall be as frontlets between thine eyes.

And thous shalt write them upon the posts of thy house, and on thy gates.

The Lord blesses His people in their goings in and comings out. Everything they set their hand to shall prosper.

Deuteronomy 7:15

And the Lord will take away from thee al sickeness, and will put none of the evil diseases of Egypt, which thou knows, upon thee, but will lay them upon all them that hate thee.

Deuteronomy 8:6

Therefore thou shalt keep the commandments of the Lord thy God, to walk in his ways, and to fear Him.

When I get my beach house, one of these will go at the front door and back door,

That all who enter or leave my be blessed in their comings and goings.

Mezuzah is of biblical origin and therefore carries great weight. “And you shall inscribe them on the doorposts (mezuzot) of our house and on your gates” (Deuteronomy 6:9; 11:20). What is to be inscribed? Divine instruction is very clear: “The words that I shall tell you this day”: that you shall love your God, believe only in Him, keep His commandments, and pass all of this on to your children.

Deuteronomy 11:20  And thous shalt write them upon the door posts of thine house, and upon thy gates.

Blessed are You, Lord our God, Ruler of the universe, who has sanctified us with His commandments and commanded us to affix a mezuzah.

After reciting the blessing, all those standing about answer “Amen.” Immediately the mezuzah is nailed or glued to the right doorpost. That’s it — a 30-second ritual that lasts the lifetime of tenure in that place….https://www.myjewishlearning.com/article/mezuzah/
