The blood from his wound ran onto the floor of the chariot. 1 Kings 22:36

They washed the chariot at a pool in Samaria where the prostitutes bathed. 1 Kings 22:38

Lord, may your blood cleanse me of all my sins. In the same way soldiers cleaned their weapons in the prostitute pool, cleanse me until I a fit to do your work. 

Carelessness is an insult to the Holy Spirit. We should have no carelessness about us, either in the way we worship God or even in the way we eat and drink. – Oswald Chambers
