When it is said
It belongs to a short service for blessing a new home, led by a priest.
Nothing in it is only for a priest to ask. You can pray it at home for your own household, on moving in or on any day.
Where it comes from
No author known
From the blessing of a new home
No one knows who wrote it, or when. The Russian book of hours ends with short services for special needs, and one is for blessing a new home. It gives a first prayer, then “another prayer”: this one. The first asks God to keep from harm those who will live there. This one asks for their whole life together.

Zacchaeus’s house
The service reads the Gospel of Zacchaeus, the tax collector Jesus visited at home. Its hymn asks that as salvation came to Zacchaeus’s house when Christ came in, He would now give His peace to this house too. Its first prayer begins the same way: God our Saviour “was pleased to enter in under the roof of Zaccheus”.

The Scripture in it
… that you may see your children’s children. Peace be upon Israel!
Then the King will say to those on His right, ‘Come, you who are blessed by My Father, inherit the kingdom prepared for you from the foundation of the world.

In Church Slavonic
Господи Боже, Владыко Вседержителю, благослови, молим Ти ся, жилище сие и вся рабы Твоя, живущия в нем, яко да, охраняеми Тобою, пребудут в мире, любви и согласии:
благослови их, яко да, исполняюще волю Твою святую, обитают зде до старости своея и узрят сыны сынов своих:
благослови их радостьми, веселием и изобилием, яко да утешают неимущих:
благослови их долголетием, яко да, угождающе Тебе, Владыце, Создателю и Спасителю, по милости Твоей внидут живущии в сем жилище и во Царствие Твое Небесное, уготованное всем творящим повеления Твоя.
Услыши нас, Всемилостиве, и благослови жилище сие и живущих в нем: яко да всегда хвалят Тя, Бога нашего, Отца и Сына и Святаго Духа, ныне и присно и во веки веков. Аминь.
