'Unawares' in the Bible

that the manslayer might flee there, who kills his neighbor unawares, and didn't hate him in time past; and that fleeing to one of these cities he might live:

This is the case of the manslayer, that shall flee there and live: whoever kills his neighbor unawares, and didn't hate him in time past;

Let destruction come on him unawares. Let his net that he has hidden catch himself. Let him fall into that destruction.
