I will cry unto God most high; unto God that performeth all things for me.
I will cry unto God. The cry to God naturally follows soul-trust in God (Psalms 57:1).
Most high - `The Most High' will lift us on high when, being sunken low, we "cry" to Him. Formidable enemies are nothingness when 'the Most High' is on our side. Compare David's committal of his cause to the Lord at Engedi (1 Samuel 24:13-16).
Unto God that performeth all things for me. God's favours already received are a pledge that He will complete His work of love 'upon х `al (H5921)] me.' The beginning is the earnest of the completion. His Word is a guarantee for the performance of "all things" that I need (cf. Psalms 57:3; Psalms 56:4; 1 Samuel 2:9; 1 Samuel 3:12; 1 Samuel 23:17; 1 Samuel 24:21; Psalms 138:8; Job 10:3; Job 10:8; Job 14:15; Philippians 1:6; Isaiah 26:12).
