'Blood' in the Bible

“Please speak in the presence of all the lords of Shechem, ‘Is it better for you that 70 men, all the sons of Jerubbaal, rule over you or that one man rule over you?’ Remember that I am your own flesh and blood.”

That the cruelty done to the threescore and ten sons of Jerubbaal might come, and their blood be laid upon Abimelech their brother, which slew them; and upon the men of Shechem, which aided him in the killing of his brethren.

And Samson said, With a red ass's mouth-bone I have made them red with blood, with a red ass's mouth-bone I have sent destruction on a thousand men.
