'Dedicating' in the Bible

Behold, I am about to build a house for the name of the Lord my God, dedicating it to Him, to burn fragrant incense before Him and to set out the showbread continually, and to offer burnt offerings morning and evening, on sabbaths and on new moons and on the appointed feasts of the Lord our God, this being required forever in Israel.

On the day after the festival ended, they convened a solemn assembly, because they had been dedicating the altar for seven days and observing the festival for seven days.
