When I was in seminary taking a course on the Psalms, another student and I chose Psalm 55. I used it to exemplify the prayer of an abused woman, having the other students sit in a room with candles, while I entered with my own candle, having put on makeup to look like I had been struck in the face many times. Here is a portion of that Psalm:
“Hear my prayer, O God; do not hide yourself from my petition. Listen to me and answer me; I have no peace, because of my cares…My heart quakes within me, and the terrors of death have fallen upon me. Fear and trembling have come over me, and horror overwhelms me. And I said, “Oh that I had wings like a dove! I would fly away and be at rest…For had it been an adversary who taunted me, then I could have borne it; or had it been an enemy who vaunted himself against me, then I could have hidden from him. But it was you, a man after my own heart, my companion, my own familiar friend. In the evening, in the morning, and at noonday, I will complain and lament, and God will hear my voice…Cast your burden upon the Lord, and he will sustain you…”
