'Joint partakers' in the Bible

Look at the Israelites--the nation and their ritual. Are not those who eat the sacrifices joint-partakers in the altar?

You cannot drink the Lord's cup and the cup of demons: you cannot be joint-partakers both in the table of the Lord and in the table of demons.

That they who are of the nations should be joint heirs, and a joint body, and joint partakers of the promise in Christ Jesus through means of the glad-message, -

According as it is right in me to have this regard in behalf of you all, - because ye have had me in your hearts, both in my bonds and in the defence and confirmation of the glad-message, all of you being, joint partakers of my favour.
