'Blood' in the Bible

The cup of blessing which we bless, is it not a communion of the blood of Christ? The bread which we break, is it not a communion of the body of Christ?

In like manner also the cup, after supper, saying, This cup is the new covenant in my blood: this do, as often as ye drink it , in remembrance of me.

Wherefore whosoever shall eat the bread or drink the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord.

Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
