a dwelling place or abode: the settled home where someone or something lives
The word names a place where someone settles and lives. Most often it is God's own dwelling: sometimes heaven, from which he looks down, answers prayer, and thunders in judgment, and sometimes the temple in Jerusalem, called his "holy habitation." It is the ordinary word for a home, lifted up to describe where God is present.
In a striking poetic turn, several psalms make God himself the dwelling place. He is not merely in the home, he is the home: the settled refuge his people have lived in across every generation. This is the sense behind the famous line, "Lord, you have been our dwelling place in all generations."
The same word also names the lairs of wild animals. When the prophets picture a city reduced to ruins, they call it a "den of jackals" or a "haunt of lions," an abandoned place fit only for beasts. One word thus stretches from the highest home imaginable to the lowest, held together by the single idea of a place that is lived in.
