This expression in English shows that there is a contrast between the people Jonah had just spoken about and himself. They paid attention to useless gods, but he would worship Yahweh. Alternate translation: "But I"
This means that Jonah would thank God while he offered a sacrifice to him. It is not clear whether Jonah planned to thank God by singing or shouting joyfully.
This can be reworded so that the abstract noun "salvation" is expressed as the verb "save." "Yahweh is the one who saves people" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
