Voice of blood
'The voice of blood,' as in Genesis 4:10, signifies violence to charity. There are several passages in the Word where the word 'voice' is used for accusation, and 'blood' is used for sins, particularly hatred. Whoever holds hatred towards his brother kills him in his heart, as the Lord teaches in Matthew 5:21-22 and elsewhere.

The multitudes who went before him, and who followed kept shouting, "Hosanna to the son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!"
