Q:

What is the possessive case and the objective case of "ye?"

I know very well that archaically, "thou" is the nominative case for the modern day "you" while "thee" is the accusative case and that there is no distinction between the nominative and accusative cases in modern English, (both "you.") I know the same for "I" and "me," "he" and "him," "she" and "her," "we" and "us," and "they" and "them," nominative and accusative respectively. However, I have scoured the Earth looking for the accusative (objective) case of "ye." I have just been assuming that it was simply just "ye," but I am searching for a definitive answer. Similarly, what is the possessive case of "ye?" Essentially, what is the word for "to all of you" and "all of your" in archaic times (the second person plural accusative and possessive pronouns?)

A:

In Early Modern English, ye was the nominative case and the objective and possessives were the familiar you (objective), your (possessive determiner) and yours (possessive pronoun). 

A:

Genesis 18:5 And I will fetch a morsel of bread, and comfort ye
your hearts; after that ye shall pass on: for therefore are ye come to your servant.
