“I lift up my eyes to the mountains— where does my help come from? My help comes from the Lord , the Maker of heaven and earth. He will not let your foot slip— he who watches over you will not slumber; indeed, he who watches over Israel will neither slumber nor sleep. The Lord watches over you— the Lord is your shade at your right hand; the sun will not harm you by day, nor the moon by night. The Lord will keep you from all harm— he will watch over your life; the Lord will watch over your coming and going both now and forevermore.”
Psalm 121:1‭-‬8

This Psalm is called a “song of ascents”. It would be sung on the way to the temple or taberncle which, during David’s time, was at the very highest point of the very highest mountain, around which the City of Jerusalem had been built! The song is written in a form call “call and response”-the leader who call, as he led the climb up the mountain: I lift up my eyes to the mountains— where does my help come from? The crowd of worshippers would answer: “My help comes from the Lord , the Maker of heaven and earth.” It was sung as reminder of Who God is and it was sung to God as a prayer. It is another great Psalm to pray back to God, simply by changing the personage of the song. (I personalize it by also changing the tense.)
God, You “will not let my foot slip— You Who watches over me will not slumber; indeed, You Who watches over Israel (America) will neither slumber nor sleep. You, Lord watches over me— the Lord is my shade at my right hand; the sun will not harm me by day, nor the moon by night. The Lord will keep me from all harm— He will watch over my life; the Lord will watch over my coming and going both now and forevermore.”
Amen.
Its great to know that the same God who watched over David, watches over me, even in our troubled times. He never changes! Think about it!
