'Mortally' in the Bible

lest the avenger of blood pursue the manslayer, while his heart is hot, and overtake him, because the way is long, and smite him mortally; whereas he was not worthy of death, since he hated him not previously.

But if any man hate his neighbour, and lie in wait for him, and rise up against him, and smite him mortally that he die, and fleeth into one of these cities:

Cursed be he that taketh reward to smite mortally shedding innocent blood! And all the people shall say, Amen.
