God told them not to defile the land with blood,and the land could not be cleansed but by the blood of him that shed it. God is still the same no one should defile the land with blood, I believe thats part of the turmoil in our society today to much blood shed!!!!
Mark, John 5:31 and John 8:18 do not contradict each other. In 5:31, Jesus is saying that, according to Jewish law, a single witness (in this case, Himself) is insufficient to establish truth (see Numbers 35:30, and especially Deuteronomy 19:15; also 2 Corinthians 13:1). In 8:18, He states that not only He, but the Father also, bears witness of Him. Thus, his witness (which agrees with that of the Father) is TRUE.
