the God who gave me vengeance and subdued peoples under me,
PSALM 18. We all know through what difficulties and almost insurmountable obstacles David came to the kingdom. Even to the time of Saul’s death he was a fugitive, and, as it were, an outlaw, and wearily passed his life in fear, amidst many threatenings and dangers of death.
Commenting on Psalm 18:1-50
"It is God that avengeth me, and subdueth the people under me." To rejoice in personal revenge is unhallowed and evil, but David viewed himself as the instrument of vengeance upon the enemies of God and his people, and had he not rejoiced in the success accorded to him he would have been worthy of censure.
In these verses, I. David looks back, with thankfulness, upon the great things which God had done for him. He had not only wrought deliverance for him, but had given him victory and success, and made him triumph over those who thought to triumph over him.
