'Blood' in the Bible

They build up Zion with blood, and Jerusalem with iniquity.

Will the Lord accept a thousand rams, or ten thousand streams of olive oil? Should I give him my firstborn child as payment for my rebellion, my offspring -- my own flesh and blood -- for my sin?

The good man is perished out of the earth: and there is none upright among men: they all lie in wait for blood; they hunt every man his brother with a net.
