'Readiness' in the Bible

Then Aaron shall lay both of his hands on the head of the live goat, and confess over it all the iniquities of the sons of Israel and all their transgressions in regard to all their sins; and he shall lay them on the head of the goat and send it away into the wilderness by the hand of a man who stands in readiness.

that their hearts may melt, and many fall at all their gates. I have given the glittering sword. Ah! It is made for striking like lightning, it is wrapped up in readiness for slaughter.
