turn not: That is, "reject not thine anointed;" or, "repulse him not," agreeably to the interpretation of this phrase in the Syriac and Arabic versions.
thine anointed: 1Ki 1:34; Psa 2:2; Isa 61:1
remember: Psa 132:1; Isa 55:3; Act 13:34
the mercies: Or, as Dr. Geddes renders, "the pious deeds of thy servant David." The Syriac has, "the good actions of thy servant."
