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 will not strike you by day, nor the moon by night. The LORD shall preserve you; He shall preserve your soul. The LORD shall preserve your going out and your return from this time forth, and forevermore... (Psalm 121:3-8)
