I will lift up mine eyes unto the hills

from whence cometh my help.
My help cometh from the LORD,
which made heaven and earth.

He will not suffer thy foot to be moved:
he that keepeth thee will not slumber.

Behold, he that keepeth Israel
shall neither slumber nor sleep.

The LORD is thy keeper:
the LORD is thy shade upon thy right hand.

The sun shall not smite thee by day,
nor the moon by night.

The LORD shall preserve thee from all evil:
he shall preserve thy soul.

The LORD shall preserve thy going out and thy coming in
from this time forth, and even for evermore.
Psalm 121
