2 My help comes from the LORD, the Maker of heaven and earth.
3 He will not let your foot slip-he who watches over you will not slumber;
4 indeed, he who watches over Israel will neither slumber nor sleep.
5 The LORD watches over you-the LORD is your shade at your right hand;
6 the sun will not harm you by day, nor the moon by night.
7 The LORD will keep you from all harm-he will watch over your life;
8 the LORD will watch over your coming and going both now and forevermore. (Psalm 121).
1-2 The psalmist is looking with great anxiety or longing to the hills. Perhaps he expects robbers to be hiding there. Or he may have looked with great anticipation if he were on a pilgrimage to Jerusalem (125:2).
The "help" the psalmist is concerned with pertains to protection, guidance, and blessing, which can only come from the Lord. He comforts himself with the thought that the LORD is "the Maker of heaven and earth." The creedal statement originally signified an apologetic statement on the LORD's sovereignty over all realms, thereby excluding any claims by pagan deities.
3-6 The ground for the psalmist's confidence lies in the further development of the doctrine of God: the guardian ("he who watches") of Israel is the guardian of every believer. He protects, guides, and blesses his own. He will be their "shade" as he protects them day and night. The intensity of his care is further amplified as he never sleeps nor slumbers. The LORD is always there to help and to protect his people.
7-8 The LORD's care extends to all adversities, as he is sovereign over all affairs of life, especially the "life" (lit., "soul") of his own child. Whatever his children do-whether they arrive at Jerusalem, go on a far journey, or return home-the Lord will "watch" over their affairs, "now and forevermore."
JESUS IS LORD.
