This is a superscription that tells about the psalm. Some scholars say that this is part of the scripture and some say that it is not. (See "What are Superscriptions in Psalms" in [Introduction to Psalms](../front/intro.md).)
Since this song is addressed to Yahweh, Yahweh can be referred to as "you." Alternate translation: "Yahweh, I will give thanks to you with all my heart" (See: [[rc://en/ta/man/jit/figs-123person]])
The noun "deeds" can be expressed with the verb "do." Alternate translation: "all the marvelous things you do" or "all the marvelous things you have done" (See: [[rc://en/ta/man/jit/figs-abstractnouns]])
