'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 the gentiles are co-heirs and of the same body and joint partakers of the promise in Christ Jesus through the gospel,

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.
