Ps.121:1 I lift up my eyes to the hills.
From where does my help come?
2 My help comes from the Lord,
who made heaven and earth.
3 He will not let your foot be moved;
he who keeps you will not slumber.
4 Behold, he who keeps Israel
will neither slumber nor sleep.
5 The Lord is your keeper;
the Lord is your shade on your right hand.
6 The sun shall not strike you by day,
nor the moon by night.
7 The Lord will keep you from all evil;
he will keep your life.
8 The Lord will keep
your going out and your coming in
from this time forth and forevermore.
Comments from the ESV Study Bible:
“The help comes from the Lord, who made heaven and earth, and therefore no other power can hinder it.”
“The verses are dominated by the word ‘keep’ (to keep, guard, watch over, attend to carefully): the Lord who keeps Israel also keeps you. This means that he will not let your foot be moved (i.e., slip as you walk), nor will he let you suffer from the dangers of day and night.”
“…the Lord is your keeper at all times; he will neither slumber no sleep. Not only is God all-powerful, he is ever-watchful. This is the confidence the faithful are to enjoy.”
