Psalm 121:1-8:

I will lift up my eyes to the hills-from whence comes my help? My help comes from the Lord, who made heaven and earth.

He will not allow your foot to be moved; He who keeps you will not slumber. Behold, He who keeps Israel shall neither slumber nor sleep.

The Lord is your keeper; the Lord is your shade at your right hand. The sun shall not strike you by day, nor the moon by night.

The Lord shall preserve you from all evil; He shall preserve your soul. The Lord shall preserve your going out and your coming in from this time forth, and even forevermore.
