Deuteronomy 20:5 What man is there that hath built a new house and hath not dedicated it.
We are not informed as to the ceremonies accompanying the dedication of a dwelling; they were probably a combination of social and devotional. The title of the thirtieth Psalm is, “A Psalm or Song at the Dedication of the House of David.” The completion of the wall of Jerusalem in the time of Nehemiah was celebrated by a dedication, at which there was great rejoicing (Neh. 12:27). The rabbis say that not only was a newly built house to be dedicated, but a house lately obtained, whether by inheritance, purchase, or gift. Houses that were not suitable for habitation, and that could not be made so, were not dedicated; but houses such as granaries and barns, that could in ease of necessity be converted into dwellings, were dedicated.
The custom of dedicating dwelling-houses was common among the ancient Egyptians, and is practiced to this day among the Hindus.
