'Blood' in the Bible

"Furthermore, you're aware of what Zeruiah's son Joab did to me and to those two commanders of the armies of Israel, Ner's son Abner and Jether's son Amasa, whom he killed, and how he shed the blood of wartime during times of peace, staining the very belt he wears around his waist and the sandals he wears on his feet.

But don't let him off unpunished, since you're a wise man and you'll know what you need to do to him. Find a way that he dies in his old age by shedding his blood."

May their blood be repaid to Joab and to his descendants forever, and may there be peace shown from the LORD forever to David, to his descendants, to his household, and to his throne."

So the prophets of Baal cried even louder and slashed themselves with swords and lances until their blood gushed out all over them, as was their custom.

Ask the king, "Did you commit murder? And now you're going to steal as well?' Also tell him, "This is what the LORD says: "Where the dogs were licking up Naboth's blood, dogs will also lick up your blood that's right yours!"'"

The battle continued on for the rest of the day while the king of Israel was propped up in front of the Arameans until the sun set, at which time he died. The blood from Ahab's wound ran down into the bottom of the chariot.

They washed the chariot by the reservoir of Samaria, and the dogs licked up his blood near where the prostitutes went to bathe, in keeping with the message that the LORD had spoken.
