Whole chapter discussed by Augustine of Hippo —
I Lift Up My Eyes to the Hills
A song of ascents.
1I lift up my eyes to the hills.
From where does my help come?
2My help comes from the LORD,
the Maker of heaven and earth.
3He will not allow your foot to slip;
your Protector will not slumber.
4Behold, the Protector of Israel
will neither slumber nor sleep.
5The LORD is your keeper;
the LORD is the shade on your right hand.
6The sun will not strike you by day,
nor the moon by night.
7The LORD will guard you from all evil;
He will preserve your soul.
8The LORD will watch over your coming and going,
both now and forevermore.
