Rid me, and deliver me - See the notes at Psalm 144:7-8. The language is here repeated. The prayer had been interrupted by the thought that the answer to it would lay the foundation for praise, and by an acknowledgment of entire dependence on God. The psalmist now, after repeating the prayer, suggests what would result from the answer to it, and dwells on the happy consequences which must follow; the bright scenes in his own reign, in the prosperity of the people, in the happiness of the nation, in domestic comforts, and in the abundance which the land would produce when these dangers should pass away, when people now engaged in the conflict of arms might return to the peaceful pursuits of life, when families would be safe in their dwellings, and when the earth cultivated in time of peace would again produce abundance, Psalm 144:12-14.

Rid me, and deliver me from the hand of strange children,.... This is repeated from Psalm 144:7; and is done to show the vehemency and importunity of the request, and the danger David was in, and his sense of it; See Gill on Psalm 144:7;
whose mouth speaketh vanity, and their right hand is a right hand of falsehood. See Gill on Psalm 144:8.
