'Guardian' in the Bible

The [mournful, inspired] oracle (a burden to be carried) concerning Dumah (Edom):Someone keeps calling to me from Seir (Edom),“Watchman, what is left of the night [of Assyrian oppression]?Watchman, what is left of the night? [How long until morning?]”

“Through the abundance of your commerceYou were internally filled with lawlessness and violence,And you sinned;Therefore I have cast you out as a profane and unholy thingFrom the mountain of God.And I have destroyed you, O covering cherub,From the midst of the stones of fire.

But I (Gabriel) will tell you what is inscribed in the writing of truth. There is no one who stands firmly with me and strengthens himself against these [hostile spirit forces] except Michael, your prince [the guardian of your nation].

For you were continually wandering like [so many] sheep, but now you have come back to the Shepherd and Guardian of your souls.
