PSALM 54 David has recorded in this psalm the prayers which he offered up to God when he heard of his having been betrayed by the Ziphites, and was reduced to a situation of extreme danger. It cannot fail to impress us with a high idea of his indomitable faith, thus to find him calling upon the name of God in the immediate prospect of death.

He was sure that he had God on his side, that God took his part (Psa 54:4); he speaks it with an air of triumph and exultation, Behold, God is my helper.
