The word of the day is…
ἡμεῖς, ἡμῶν, ἡμῖν, ἡμᾶς
Greek, hēmeis, hēmōn, hēmīn, hēmās, 1. personal pronoun, “we, us” (with forms in the plural nominative, genitive, dative and accusative, respectively)
We will cover forms of the singular first person personal pronoun, ἐγώ, and the singular second person personal pronoun, σύ, soon enough in my foray into the words found in the book of Hebrews. Not sure yet if the plural second person pronoun is used there.
As for the third person personal pronoun, Classical Greek employs the forms of the demonstratives in the nominative, with the other cases being forms of αὐτός.
