This psalm is a song of praise. Parallelism is common in Hebrew poetry. (See: [[rc://en/ta/man/jit/writing-poetry]] and [[rc://en/ta/man/jit/figs-parallelism]])
This speaks of praise as if it were a person who could act on its own. Alternate translation: "To you alone, God in Zion, we will offer our praise" (See: [[rc://en/ta/man/jit/figs-personification]])
This can be stated in active form. Alternate translation: "we will do what we have promised you that we would do" (See: [[rc://en/ta/man/jit/figs-activepassive]])
