Psalm 121 Mar. 13 A Song of Ascents.  1I will lift up my eyes to the hills. Where does my help come from? 2My help comes from Yahweh, who made heaven and earth. 3He will not allow your foot to be moved; He who keeps you will not slumber. 4Behold, He who keeps Israel will neither slumber nor sleep. 5Yahweh is your keeper, Yahweh is your shade on your right hand. 6The sun will not harm you by day, nor the moon by night. 7Yahweh will keep you from all evil; He will keep your soul. 8Yahweh will keep your going out and your coming in from this time forth and forever.   

Commentary

121:2 Belief in God as creator (rather than in atheistic evolution) inspires our faith in His ability to likewise creatively deliver us from the crises of our lives.
121:5 Yahweh is your shade- Alluding to how on the wilderness journey, God provided the pillar of cloud as a shade to Israel (105:39). Our lives are repeatedly described in the Bible as being like the wilderness journey towards the promised land. The allusion is also to how God was a shade or shadow to Hezekiah when the shadow on the sundial went backward (Is. 38:8); what He did for Hezekiah He can in essence do for all His people.
