These two clauses have similar meanings and are used together to emphasize that God has heard his prayer. AT: "But God has truly heard my prayer" (See: [[rc://en/ta/man/translate/figs-parallelism]])
The phrase "has not turned away" is understood from the previous phrase and can be repeated here. The idea of "his covenant faithfulness" can be translated with the phrase "being faithful to his covenant." AT: "and has not turned away his covenant faithfulness from me" or "and has not stopped being faithful to his covenant with me" (See: [[rc://en/ta/man/translate/figs-abstractnouns]])
