ISB ~ Matthew 18 v10

their angels:Scripture portrays God’s angels as protectors, guides, and helpers of his people (Tob 12:15; Job 33:23-24; Ps 34:7; 91:11; Acts 12:15; Heb 1:14). The elect angels already participate in glory as they behold the face of God in heaven (CCC 329, 336).

• This verse is traditionally cited as biblical evidence for guardian angels. Several Church Fathers teach that God assigns everyone an angel to watch over him throughout life.
