Psalm 121 Help For Those Who Look For It.
This psalm is written from the perspective of one travelling to the hill country where Zion is perched on a hill. The psalmist knows the answer to his question, because this is partly the reason for his journey. Some found comfort in the hills themselves, but the saints look to the LORD Himself (v. 1 Cf. Jer. 3:23). He who has made heaven and earth, is the LORD of the covenant (v. 2 Cf. Ps. 124:8). The LORD will never be caught sleeping or be unaware of the needs of His people. He will guide and protect us on our life journey (vv. 3-4 Cf. Ps. 127:1; Pr. 3:6, 23, 26). “The LORD is your keeper; the LORD is your shade at your right hand.” (v. 5)
“At your right hand,” is expressive of productivity and authority (Cf. Ps. 16:8). The LORD upholds the place and work of His people in the world. The presence of the LORD is also a comfort and protection to His people-a shade that goes with us (vv. 5b-6 Cf. Is. 49:10). “As a person’s shadow is always with him, so is God with His people. The metaphor comes from ancient treaty language and has covenantal overtones.” (NGSB, p.897) He preserves and keeps His own throughout their lives (vv. 7-8 Cf. Dt. 28:6; Ps. 41:2; Pr. 2:8).
