Mine enemies would daily swallow me up: for they be many that fight against me, O thou most High. O thou Most High - מרום marom. I do not think that this word expresses any attribute of God, or indeed is at all addressed to him. It signifies, literally, from on high, or froen a high or elevated place: "For the multitudes fight against me from the high or elevated place;" the place of authority - the court and cabinet of Saul.
Most of the Versions begin the next verse with this word: "From the light of the day, though I fear, yet will I trust in thee." From the time that persecution waxes hot against me, though I often am seized with fear, yet I am enabled to maintain my trust in thee. Dr. Kennicott thinks there is a corruption here, and proposes to read: "I look upwards all the day long."
