Question: where in the bible does it speak of guardian angels?
Answer: In the books of the Hebrew Bible and Old Testament Psalm 33:8 and 34:5 — 34:7 and 35:6 in Protestant Bibles). The belief that angels can be guides and intercessors for men can be found in Job 33:23-6, and in Daniel 10:13 angels seem to be assigned to certain countries.
