Psalm 91 was written by Moses when the children of Israel were in the wilderness, the scripture was aimed at comforting the church during the 40 years curse. This chapter is conceived as very powerful today, most Christians recite it on daily basis, this book, however, attempts at unravelling the mysteries behind it and my prayer is that the holy spirit will help us in the explanation in the name of Jesus.It remains a powerful psalm in the bible, most children of God memorize, always recite and it is adjudged to be very powerful, there have been a series of testimonies shared concerning its efficacy. This psalm was composed by Moses while ascending into the cloud hovering over mount Sinai(Exodus 24:18), at which time he recited these words as protection from the angels of destruction.
