Is there evidence of guardian angels?

Can anyone provide me scriptural evidence for guardian angels?

Here are a few verses:

See that you do not despise one of these little ones; for I tell you that in heaven their angels always behold the face of my Father who is in heaven. (Mt 18:10)

The angel of the LORD encamps around those who fear him, and delivers them. (Ps 34:7)

For he will give his angels charge of you to guard you in all your ways. (Ps 91:11)
