'Shouldest' in the Bible

So he departed from Elisha, and came to his master; who said to him, What said Elisha to thee? And he answered, He told me that thou shouldest surely recover.

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 thine heart hath lifted thee up: glory of this, and tarry at home: for why shouldest thou meddle to thy hurt, that thou shouldest fall, even thou, and Judah with thee?

Hast thou not heard long ago how I have done it, and of ancient times that I have formed it? now have I brought it to pass, that thou shouldest be to lay waste fenced cities into ruinous heaps.
