First Reading for Memorial of the Guardian Angels - Daily Catholic Mass Reading

Thus says the LORD:

"See, I am sending an angel before you, to guard you on the way and bring you to the place I have prepared.

Be attentive to him and heed his voice.

Do not rebel against him, for he will not forgive your sin.

My authority resides in him.

If you heed his voice and carry out all I tell you, I will be an enemy to your enemies and a foe to your foes.

"My angel will go before you and bring you to the Amorites, Hittites, Perizzites, Canaanites, Hivites, and Jebusites; and I will wipe them out."
