He will reward my enemies with evil. In Your faithfulness, destroy them.
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.
Commenting on Psalm 54:1-7
He shall reward evil unto mine enemies. They worked for evil, and they shall have their wages. It cannot be that malice should go unavenged. It were cruelty to the good to be lenient to their persecutors. It is appointed, and so it must ever be, that those who shoot upward the arrows of malice shall find them fall upon themselves.
We have here the lively actings of David's faith in his prayer, by which he was assured that the issue would be comfortable, though the attempt upon him was formidable. I. 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.
