'Shouldest' in the Bible

And the man of God was wroth with him, and said, Thou shouldest have smitten five or six times: then hadst thou smitten Syria till thou hadst consumed it, whereas now thou shalt smite Syria but thrice.

Thou hast indeed smitten Edom, and thy heart hath lifted thee up: glory thereof, and abide at home; for why shouldest thou meddle to thy hurt, that thou shouldest fall, even thou, and Judah with thee?
