Alternate translation: "It was as though you had adopted me right when I was born" (See: rc://en/ta/man/translate/figs-idiom and rc://en/ta/man/translate/figs-activepassive)

you are my God

This implies that Yahweh has always taken care of the writer. Alternate translation: "you, God, have taken care of me" (See: rc://en/ta/man/translate/figs-explicit)

since I was in my mother's womb
